ScoreFun: Log Likelihood Gradient of Logistic Box-Cox

In ubclxing/lboxcox: Implementation of Logistic Box-Cox Regression

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'
