This paper describes an Arc add-in for inverse gaussian generalized linear
Generalized linear models based on the Inverse Gaussian distribution are not
use as frequently as other generalized linear models, and so they are not
included in the basic distribution of Arc. However, adding them is
straightforward, and code for this purpose is available.
Download the file invgau.lsp for
Windows or Unix, or for
Place it in the Extras directory in
your Arc directory. If you are using Unix, either place this file in
/usr/local/lib/Arc/Extras, or in an Extras directory where you start Arc.
The file will be loaded automatically whenever you start Arc.
P. McCullagh and J. Nelder (1989), Generalized Linear Models, 2nd ed.,
p. 30, briefly summarize the properties of these models. More complete
discussions are given by

If invgau.lsp is loaded, then a menu item is added to the Graph&Fit menu, and
it is used like any other generalized linear model menu item.
