matr_glob {MultiLCIRT}

Matrices to compute generalized logits

Description

It provides the matrices used to compute a vector of generalized logits on the basis of a vector of probabilities according to the formula Co*log(Ma*p); this is an internal function.

Arguments

l

number of response categories

type

type of logit (l = local-logits, g = global-logits)

Value

Co

matrix of contrasts

Ma

marginalization matrix
