In marqLevAlg: A Parallelized General-Purpose Optimization Based on Marquardt-Levenberg Algorithm

Gradient of the log-likelihood of a linear mixed model with random intercept

Description

Gradient of the log-likelihood of a linear mixed model with random intercept

Usage

gradLMM(b, Y, X, ni)

Arguments

b	numeric vector specifying the parameter's values in the following order : first the fixed effects and then the standard deviation of the random intercept and of the independent error
Y	numeric vector including the dependent outcome vector ordered by subject
X	numeric matrix including the covariates
ni	interger vector giving the number of repeated measures for each subject

Value

a vector containing the gradient of the log-likelihood of the linear mixed model at point b
