McCullagh_compute_lambda

Computes lambda, log of cumulative odds.

Fit a variety of models to two-way tables with ordered categories.
Most of the models are appropriate to apply to tables of that have correlated ordered
response categories. There is a particular interest in rater data and models for rescore
tables. Some utility functions (e.g., Cohen's kappa and weighted kappa) support
more general work on rater agreement.
Because the names of the models are very similar, the functions that implement them are
organized by last name of the primary author of the article or book that suggested the model,
with the name of the function beginning with that author's name and an underscore. This
may make some models more difficult to locate if one doesn't have the original sources. The
vignettes and tests can help to locate models of interest. For more dertaiils see the following references:
