prmu: Estimated mean and probabilities for Model 1

Description

This function calculates the estimated probabilities and the estimated mean of the response variable, in the multinomial mixed model with one independent random effect in each category of the response variable (Model 1).

Usage

prmu(M, Xk, beta, u)

Arguments

M

vector with the area sample sizes.

Xk

list of matrices with the auxiliary variables per category obtained from data.mme. The dimension of the list is the number of domains.

beta

fixed effects obtained from modelfit1.

u

values of random effects obtained from modelfit1.

Value

A list containing the following components:

Estimated.probabilities

matrix with the estimated probabilities for the categories of response variable.

mean

matrix with the estimated mean of the response variable.

eta

matrix with the estimated log-rates of the probabilities of each category over the reference category.
