In lcpm: Ordinal Outcomes: Generalized Linear Models with the Log Link

Description

lcpmMinusloglik provides the negative of the log-likelihood function for a Generalized Linear Model with a log link and ordinal outcomes to be minimized in functions lcpm and ppm.

Usage

lcpmMinusloglik(betapar, Xa1, XaJ, Xaj1, Xaj2)

Arguments

betapar	a vector of values.
Xa1	matrix of covariates for all subjects with the lowest ordinal outcome value 1.
XaJ	matrix of covariates for all subjects with the largest ordinal outcome value J.
Xaj1	matrix of covariates for all subjects with the ordinal outcomes with value 1 < j < J.
Xaj2	matrix of covariates for all subjects with the ordinal outcome with value 1 < j < J but lagged by 1.

Value

value of the negative log-likelihood evaluated at betapar
