glm.lld: Log-likelihood derivatives for GLM

Description

Computes first and second derivatives of the individual log-likelihood with respect to the linear predictor. Currently only the gaussian (with identity link) and the bernoulli family (with logit and probit links) are implemented.

Usage

glm.lld(eta, y, family="gaussian", link="identity", k=1)

Arguments

eta

n x 1, linear predictors

y

n x 1, responses

family

text string, family of distributions (e.g. "gaussian" or "bernoulli", see details for glm.ll)

link

text string, link function (depending on family, see details for glm.ll)

k

integer > 0, parameter for the negative binomial

Value
