Estimation of multinomial mixture distributions parameters

This function performs maximum likelihood inference for multinomial mixture distributions.

coef_mixtures(Mp, Np)

Arguments

Mp	a matrix of mixtures (a row matrix if a vector)
Np	a matrix of bases (a row matrix if a vector)

Value

This function returns a list of maximum likelihood estimates for the cells of a mixture distribution:

P matrix of cell probabilities estimates for mixtures

PI matrix of mixture probabilities

GAM matrix of cell probabilities estimates for bases
