effe01 function

Auxiliary function for the log-likelihood estimation of CUB models

Compute the opposite of the scalar function that is maximized when running the E-M algorithm for CUB models with covariates for the feeling parameter.

effe01(gama, esterno01, m)

Arguments

• gama: Vector of the starting values of the parameters to be estimated
• esterno01: A matrix binding together the vector of the posterior probabilities that each observation has been generated by the first component distribution of the mixture, the ordinal data and the matrix of the selected covariates accounting for an intercept term

Details

It is called as an argument for optim within CUB function for models with covariates for feeling or for both feeling and uncertainty
