mgee {saws}

Modified gee function to output extra objects for saws

Description

This function calls the gee function from the gee package, then applies the geeUOmega function to it to create a score matrix (i.e., estimating equation) and information array (i.e., minus the derivative of the estimating equation). Since the mgee function just calls the gee function all help for gee applies to mgee.

Usage

mgee(formula = formula(data), id = id, data = parent.frame(),
    subset, na.action, R = NULL, b = NULL, tol = 0.001, 
    maxiter = 25, family = gaussian, corstr = "independence", 
    Mv = 1, silent = TRUE, contrasts = NULL, scale.fix = FALSE,
    scale.value = 1, v4.4compat = FALSE)
