geex-package: geex: M-estimation API

Description Details Goals Author(s) See Also


geex provides an extensible API for estimating parameters and their covariance from a set of estimating functions (M-estimation). M-estimation theory has a long history [see reference in the M-estimation bibliography: For an excellent introduction, see the primer by L.A. Stefanski and D.D. Boos, "The Calculus of M-estimation" (The American Statistician (2002), 56(1), 29-38) (


M-estimation encompasses a broad swath of statistical estimators and ideas including:

geex can implement all of these using a user-defined estimating function.

To learn more about geex, see the package vignettes: browseVignettes(package = 'geex').


If you can specify a set of unbiased estimating equations, geex does the rest. The goals of geex are simply:

geex does not, by itself, necessarily aim to be fast nor precise. Such goals are left to the user to implement or confirm.
