The simex Package

This pakage for R implements the simex procedure developed by Cook & Stefanski for dealing with measurement error models, as well as the mcsimex for misclassified data developed by Küchenhoff, Mwalili and Lesaffre.

Installation

It can be found on CRAN and installed with

R install.packages("simex")

The most current version can be installed via

R devtools::install_github("wolfganglederer/simex")

simex NEWS:

Version 1.8:

  • coxph from survival is now supported (Rasmus Froberg Brøndum) & PR by Heidi
  • website added (Wolfgang)
  • smaller fixes (Wolfgang)

Version 1.7:

(by Wolfgang Lederer)

  • Option fitting.method in function simex() now really works properly for "linear" (Wolfgang)
  • Smaller documentation fixes (Wolfgang)
  • Uploaded to Github and moved documentation to roxygen2 (Wolfgang)
  • Added support for proportional odds logistic regression (polr from library MASS) (Chris Lawrence)

Version 1.5:

(by Heidi Seibold & Wolfgang Lederer)

  • Option fitting.method in function simex() now works properly for "linear" (Wolfgang)
  • Measurement errors may now be heteroscedastic. Therefore the input-type had to be changed. The measurement error now has to be a matrix. (Heidi)
  • The functions simex and print.summary.simex were adjusted. (Heidi)

Version 1.4:

(by Ph. Grosjean phgrosjean@sciviews.org)

  • Object classes were renamed 'simex' and 'mcsimex' to match their constructor's names simex() and mcsimex().
  • Interface of mcsimex() has been homogenized with the one of simex(), with fitting.method at the sixth place instead of last one.
  • print() methods now return x invisibly, as they are supposed to do.
  • predict() methods failed when newdata was not provided. Fixed.
  • refit() is now a generic function with methods for objects 'simex' and 'mcsimex'. Its arguments have been reworked to match arguments of simex() and mcsimex() functions (jackknife becomes jackknife.estimation).
  • A NAMESPACE is added and functions that are not supposed to be used by the end-user are now hidden in the namespace (construct.s(), fit.log() and fit.nls()).
  • Documentation has been rewritten to match current R standards. Methods are now documented in the same page as the object creator. 'Overview' is rewritten and renamed 'simex-package'.
