Log Likelihood Gradient of Logistic Box-Cox

Description

This function gives the gradient of the log likelihood of the Box-Cox model. Main purpose is to be an input to the maxLik function.

Usage

ScoreFun(bb, ixx, iyy, iw, iZZ)

Arguments

bb

initial values for the intercept and slope coefficients

ixx

continuous predictor

iyy

binary outcome

iw

sample weight

iZZ

covariates to be incorporated in the model

Value

the gradient of the log likelihood estimate for the coefficients in 'bb'
