##### Introduction to the StatMod Package

This library packages together those functions, other than those for microarray data analysis, which I wish to make public. A change-log for this package is available from http://www.statsci.org/r/changelog.txt. Contributions to this library have also been made by Paul Bagshaw, Centre National d'Etudes des Telecommunications (DIH/DIPS), France (qinvgauss), and Trevor Park, Department of Statistics, University of Florida (rinvgauss).

##### Generalized Linear Models

tweedie, canonic.digamma, unitdeviance.digamma, varfun.digamma, cumulant.digamma, d2cumulant.digamma, meanval.digamma and logmdigamma are functions to fit non-standard generalized linear models related to the gamma distribution. qres implements randomized quantile residuals for generalized linear models.

##### Growth Curves

compareGrowthCurves, compareTwoGrowthCurves and meanT are functions to test for differences between growth curves with repeated measurements on subjects.

##### Limiting Dilution Analysis

limdil implements limiting dilution analysis using complemenary log-log binomial generalized linear model regression, with some improvements on previous programs.

##### Probability Distributions

qinvgauss, dinvgauss, pinvgauss and rinvgauss perform probability calculations for the inverse Gaussian distribution. gauss.quad and gauss.quad.prob compute Gaussian Quadrature with probability distributions.

##### Tests

hommel.test performs Hommel's multiple comparison tests. power.fisher.test computes the power of Fisher's Exact Test for comparing proportions. sage.test is a fast approximation to Fisher's exact test for each tag for comparing two Serial Analysis of Gene Expression (SAGE) libraries.

##### Variance Models

mixedModel2, mixedModel2Fit and glmgam.fit fit mixed linear models. remlscore and remlscoregamma fit heteroscedastic and varying dispersion models by REML. welding is an example data set.

##### Matrix Computations

matvec and vecmat facilitate multiplying matrices by vectors.
