Log-likelihood function for the fixed-effects model

Description

Log-likelihood function for the fixed-effects model

Usage

1
negloglik_glf(par, v, d.matrix, wts, len_beta)

Arguments

par

vector of regression coefficients, and M, B, T, (offset, slope and symmetry of the g function)

v

vector of standardized scores from the continuous ordinal scale

d.matrix

design matrix (fixed effects)

wts

optional case weights

len_beta

length of the regression coefficients vector

Details

This function computes minus the log-likelihood function for a fixed-effects model using the generalized logistic function as g function and the logit link function. It is used internally to fit the model and should not be of interest of the user.

Value

Minus the log-likelihood at parameter values par
