Package simex
is an implementation of the SIMEX–algorithm by Cook
and Stephanski and the MCSIMEX–Algorithm by Küchenhof, Mwalili and Lesaffre.
Package: | simex |
Type: | Package |
Version: | 1.4 |
Date: | 2009-04-19 |
License: | GPL 2 or above |
LazyLoad: | yes |
The package includes first of all the implementation for the SIMEX– and MCSIMEX–Algorithms. Jackknife and asymptotic variance estimation are implemented. Various methods and analytic tools are provided for a simple and fast access to the SIMEX– and MCSIMEX–Algorithm.
Functions simex()
and mcsimex()
can be used on models issued
from lm()
, glm()
with asymtotic estimation.
Models from nls()
, gam()
(package mgcv),
lme()
and nlme()
(package nlme) can also be corrected with
these algorithms, but without asymptotic estimations.
