A Unified Framework for Specification Tests of Continuous Treatment Effect Models

Wei Huang, Oliver Linton & Zheng Zhang
We propose a general framework for the specification testing of continuous treatment effect models. We assume a general residual function, which includes the average and quantile treatment effect models as special cases. The null models are identified under the unconfoundedness condition and contain a nonparametric weighting function. We propose a test statistic for the null model in which the weighting function is estimated by solving an expanding set of moment equations. We establish the asymptotic...

From Black Box to Shining Spotlight: Using Random Forest Prediction Intervals to Illuminate the Impact of Assumptions in Linear Regression

Andrew J. Sage, Yang Liu & Joe Sato
We introduce a pair of Shiny web applications that allow users to visualize random forest prediction intervals alongside those produced by linear regression models. The apps are designed to help undergraduate students deepen their understanding of the role that assumptions play in statistical modeling by comparing and contrasting intervals produced by regression models with those produced by more flexible algorithmic techniques. We describe the mechanics of each approach, illustrate the features of the apps, provide...

Nonparametric prediction distribution from resolution-wise regression with heterogeneous data

Jialu Li, Wan Zhang, Peiyao Wang, Qizhai Li, Kai Zhang & Yufeng Liu
Modeling and inference for heterogeneous data have gained great interest recently due to rapid developments in personalized marketing. Most existing regression approaches are based on the conditional mean and may require additional cluster information to accommodate data heterogeneity. In this paper, we propose a novel nonparametric resolution-wise regression procedure to provide an estimated distribution of the response instead of one single value. We achieve this by decomposing the information of the response and the predictors...

Zimmermann, Julien Adjedj, Nils Witt, Barry Hennigan, Bon-Kwon Koo, Akiko Maehara, Mitsuaki Matsumura, Emanuele Barbato, Giovanni Esposito, Bruno Trimarco, Gilles Rioufol, Seung-Jung Park, Hyoung-Mo Yang, Sérgio B. Baptista, George S. Chrysant, Antonio M. Leone, Colin Berry, Bernard De Bruyne, K. Lance Gould, Richard L. Kirkeeide, Keith G. Oldroyd, Nico H. J. Pijls, William F. Fearon … & Nico H.J. Pijls
OBJECTIVES: We compared the diagnostic performance with adenosine-derived fractional flow reserve (FFR) #0.8 of contrast-based FFR (cFFR), resting distal pressure (Pd)/aortic pressure (Pa), and the instantaneous wave-free ratio (iFR). BACKGROUND: FFR objectively identifies lesions that benefit from medical therapy versus revascularization. However, FFR requires maximal vasodilation, usually achieved with adenosine. Radiographic contrast injection causes submaximal coronary hyperemia. Therefore, intracoronary contrast could provide an easy and inexpensive tool for predicting FFR. METHODS: We recruited patients undergoing...

Prediction of intrahepatic cholestasis of pregnancy in the first 20 weeks of pregnancy

Xinyuan Zhang, Yu Chen, Stephen Salerno, Yi Li, Libin Zhou, Xiaoxi Zeng & Huafeng Li
Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-specific liver disease associated with a significant risk of fetal complications including pre-term delivery and fetal death. Typically, it was diagnosed in the third trimester of pregnancy. This study utilized characteristics from routine maternal examinations in the first 20 weeks’ gestation to predict ICP in pregnant women. This is a retrospective case-control study. 13,329 medical records were collected on pregnant women presenting to the West China Second University...

Data from: The evolution of locomotor rhythmicity in tetrapods

Callum F. Ross, Richard W. Blob, David R. Carrier, Monica A. Daley, Stephen M. Deban, Brigitte Demes, Janaya L. Gripper, Jose Iriarte-Diaz, Brandon Michael Kilbourne, Tobias Landberg, John D. Polk, Nadja Schilling & Bieke Vanhooydonck
Differences in rhythmicity (relative variance in cycle period) between mammal, fish, and lizard feeding systems have been hypothesized to be associated with differences in their sensorimotor control systems. We tested this hypothesis by examining whether the locomotion of tachymetabolic tetrapods (birds and mammals) is more rhythmic than that of bradymetabolic tetrapods (lizards, alligators, turtles, salamanders). Species averages of intra-individual coefficients of variation in cycle period were compared while controlling for gait and substrate. Variance in...

Data from: Selection and sex-biased dispersal in a coastal shark: the influence of philopatry on adaptive variation

David S. Portnoy, Jonathan B. Puritz, Christopher M. Hollenbeck, James Gelsleichter, Demian Chapman & John R. Gold
Sex-biased dispersal is expected to homogenize nuclear genetic variation relative to variation in genetic material inherited through the philopatric sex. When site fidelity occurs across a heterogeneous environment, local selective regimes may alter this pattern. We assessed spatial patterns of variation in nuclear-encoded, single nucleotide polymorphisms (SNPs) and sequences of the mitochondrial control region in bonnethead sharks (Sphyrna tiburo), a species thought to exhibit female philopatry, collected from summer habitats used for gestation. Geographic patterns...

Data from: Genetic differentiation but no reduction in genetic diversity at the northern range edge of two species with different dispersal modes

Abigail E. Cahill & Jeffrey S. Levinton
Theory predicts that genetic variation should be reduced at range margins, but empirical support is equivocal. Here, we used genotyping-by-sequencing technology to investigate genetic variation in central and marginal populations of two species in the marine gastropod genus Crepidula. These two species have different development and dispersal types, and might therefore show different spatial patterns of genetic variation. Both allelic richness and the proportion of private alleles were highest in the most central populations of...

Data from: Bats (Chiroptera: Noctilionoidea) challenge a recent origin of extant neotropical diversity

Danny Rojas, Omar M. Warsi & Liliana M. Dávalos
The mechanisms underlying the high extant biodiversity in the Neotropics have been controversial since the 19th century. Support for the influence of period-specific changes on diversification often rests on detecting more speciation events during a particular period. The timing of speciation events may reflect the influence of incomplete taxon sampling, protracted speciation, and null processes of lineage accumulation. Here we assess the influence of these factors on the timing of speciation with new multilocus data...

Data from: Predicting species’ vulnerability in a massively perturbed system: the fishes of Lake Turkana, Kenya

Natasha J. Gownaris, Ellen K. Pikitch, William O. Ojwang, Robert Michener & Les Kaufman
Background and Trophic Diversity Study: Lake Turkana is an understudied desert lake shared by Kenya and Ethiopia. This system is at the precipice of large-scale changes in ecological function due to climate change and economic development along its major inflowing river, the Omo River. To anticipate response by the fish community to these changes, we quantified trophic diversity for seven ecological disparate species (Alestes baremose, Hydrocynus forskalli, Labeo horie, Lates niloticus, Oreochromis niloticus, Synodontis schall,...

Data from: Mek1 down regulates Rad51 activity during yeast meiosis by phosphorylation of Hed1

Tracy L. Callender, Raphaelle Laureau, Lihong Wan, Xiangyu Chen, Rima Sandhu, Saif Laljee, Sai Zhou, Ray T. Suhandynata, Evelyn Prugar, William A. Gaines, YoungHo Kwon, G. Valentin Börner, Alain Nicolas, Aaron M. Neiman & Nancy M. Hollingsworth
During meiosis, programmed double strand breaks (DSBs) are repaired preferentially between homologs to generate crossovers that promote proper chromosome segregation at Meiosis I. In many organisms, there are two strand exchange proteins, Rad51 and the meiosis-specific Dmc1, required for interhomolog (IH) bias. This bias requires the presence, but not the strand exchange activity of Rad51, while Dmc1 is responsible for the bulk of meiotic recombination. How these activities are regulated is less well established. In...

Data from: Increased susceptibility to fungal disease accompanies adaptation to drought in Brassica rapa

Niamh B. O'Hara, Joshua S. Rest & Steven J. Franks
Recent studies have demonstrated adaptive evolutionary responses to climate change, but little is known about how these responses may influence ecological interactions with other organisms, including natural enemies. We used a resurrection experiment in the greenhouse to examine the effect of evolutionary responses to drought on the susceptibility of Brassica rapa plants to a fungal pathogen, Alternaria brassicae. In agreement with previous studies in this population, we found an evolutionary shift to earlier flowering post-drought,...

Siddall, Andrew Tilker, Carl Traeholt, Nicholas Wilkinson, Paul Woodcock, Douglas W. Yu, Mads Frost Bertelsen … & Ida Baerholm Schnell
The use of environmental DNA (eDNA) has become an applicable non-invasive tool with which to obtain information about biodiversity. A sub-discipline of eDNA is iDNA (invertebrate-derived DNA), where genetic material ingested by invertebrates is used to characterise the biodiversity of the species that served as hosts. While promising, these techniques are still in their infancy, as they have only been explored on limited numbers of samples from only a single or a few different locations....

Data from: Recent extinctions disturb path to equilibrium diversity in Caribbean bats

Luis Valente, Rampal Etienne & Liliana Dávalos
Islands are ideal systems to reconstruct changes in biodiversity and reveal the influence of humans on natural communities. While theory predicts biodiversity on islands tends towards equilibrium, the recent extinction of large proportions of island biotas complicates testing this model. The well-preserved subfossil record of Caribbean bats provides a rare opportunity to model diversity dynamics in an insular community. Here we reconstruct the diversity trajectory in noctilionoid bats of the Greater Antilles by applying a...

Gibbon genome (Nleu3.0) custom gene annotation file

Mariam Okhovat, Kimberly A. Nevonen, Brett A. Davis, Pryce Michener, Samantha Ward, Mark Milhaven, Lana Harshman, Ajuni Sohota, Jason D. Fernandes, Sofie R. Salama, Rachel J. O'Neill, Nadav Ahituv, Krishna R. Veeramah & Lucia Carbone
Co-option of transposable elements (TEs) to become part of existing or new enhancers is an important mechanism for evolution of gene regulation. However, contributions of lineage-specific TE insertions to recent regulatory adaptations remain poorly understood. Gibbons present a suitable model to study these contributions as they have evolved a lineage-specific TE called LAVA, which is still active in the gibbon genome. The LAVA retrotransposon is thought to have played a role in the emergence of...

Data from: Late Cretaceous bird from Madagascar reveals unique development of beaks

Patrick O'Connor, Alan Turner, Joseph Groenke, Ryan Felice, Raymond Rogers, David Krause & Lydia Rahantarisoa
Mesozoic birds display considerable diversity in size, flight adaptations and feather organization, but exhibit relatively conserved patterns of beak shape and development. Although Neornithine (that is, crown group) birds also exhibit constraint on facial development, they have comparatively diverse beak morphologies associated with a range of feeding and behavioural ecologies, in contrast to Mesozoic birds. Here we describe a crow-sized stem bird, Falcatakely forsterae gen. et sp. nov., from the Late Cretaceous epoch of Madagascar...
