NPML estimation in R

This web site contains R code (and documentation) for the fitting of overdispersed generalized linear models or variance component models with Gaussian quadrature (GQ) or Nonparametric maximum likelihood (NPML). In the special case that no covariates are specified, this reduces to fitting exponential family mixture models.

With version 0.30, the first 'real' package is provided (i.e. a file in *.tar.gz form that would pass R CMD check), and the package name changed from npml to npmlreg.

From version 0.40 on, new versions are only available on CRAN !!! The record of updates and changes will be maintained.

At this site can be found:

• The npmlreg package in source (for non-Windows users) and binary (for Windows-users) distribution, version 0.38 .
  • Previous versions.
• The R Documentation files.
• The npmlreg manual.
• The "Vignette": NPML-Estimation for random effect models in R with R source code .

The R functions alldist and allvc contained in this package are based on the homonymous GLIM 4 functions. Translated to R and further extended by Jochen Einbeck, Ross Darnell, and John Hinde (2006). The work was supported by Science Foundation Ireland (SFI).
