L'interpolazione razionale e la sua validità

M. Passaquindici & G. Barbieri
The rational interpolation can be used to correct anomalous values or to add missing values in a distribution of n points. Applying this method it is possible to identify a function passing by any n given points. The function is given by F(x)=S(x)/T(x) where S(x) and T(x) are two rational polynomials in x whose degrees depend on n. In this paper we present an interpolating method and we evaluate the statistical validity of the method...
