ScoreFun: ScoreFun

In LBC: Logistic Box Cox

Description

caculate the gradient value for Maximum Likelihood Estimates in LBC model

Usage

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

Arguments

bb	initial values for the intercept and slope coefficients
ixx	continuous predictor
iyy	binary outcome
iw	the weighted parameter
iZZ	covariates to be incorporated in the model

Value

a numeric gradient value of the corresponding individual observation.

Examples

iZZ <- matrix(0,100,10)
ixx <- matrix(0,100,1)
iyy <- matrix(0,100,1)
iw <-matrix(0,100,1)
# ixx: continuous predictor
# iyy: binary outcome
# iZZ: covariates to be incorporated in the model
# iw:  The weighted parameter
# myLBC <-
#   maxLik(
 #    logLik = LogLikeFun,
 #    grad = ScoreFun,
 #   start = inits,
 #   ixx = ixx,
 #   iyy = iyy,
 #   iw = iw,
 #   iZZ = as.matrix(iZZ)
 # )
# as.matrix returns all values of iZZ as a matrix
