We propose an extension of graphical log-linear models to allow for symmetry constraints on some interaction parameters that represent homologous factors. The conditional independence structure of ...

Polynomial interpolation to analytic functions can be very accurate, depending on the distribution of the interpolation nodes. However, in equispaced nodes and the like, besides being badly ...

It is sometimes necessary to perform linear interpolation or “blending” of two vectors. For example, this is done to “mix” two audio waveforms or blend two images. The equation is: For each element of ...
