[R] VGAM package released on CRAN
Dear useRs, upon request, the VGAM package (currently version 0.7-1) has been officially released on CRAN (the package has been at my website http://www.stat.auckland.ac.nz/~yee/VGAM for a number of years now). VGAM implements a general framework for several classes of regression models using iteratively reweighted least squares (IRLS). The key ideas are Fisher scoring, generalized linear and additive models, IRLS and vector smoothing. It is a large R package that fits many models and distributions, usually by maximum likelihood estimation. See below for a partial listing, or better, http://www.stat.auckland.ac.nz/~yee/VGAM/doc/VGAMrefcard.pdf. Some broad categories are categorical data analysis, LMS quantile regression, extreme value models, univariate and continuous distributions. The package is under continual development and definitely not complete yet. Until then it should probably be considered 'alpha software'. Nothing is cast in iron yet, so please expect lots of changes if you use it. I hope to add more functionality to certain parts of the package, especially relating to inference and model selection, soon. Re. support, this is minimal. I first have to apologize that it won't be possible for me to answer every e-mail I receive. Sorry about this. If you use VGAM please consult the online help plus the incomplete documentation found at my website. Additionally, other technical details can be found in the journal articles. On the positive side, a monographs is in the making, however it is expected to be finished in quite a while :) Suggestions, bug reports and other comments are very welcome.
