R packages - Sep 2005 - New package for grouped data models

Dear R-users,

We'd like to announce the release of our new package "grouped" 
(available from CRAN), for fitting models for grouped or coarse data, 
under the Coarsened At Random assumption. This is useful in cases 
where the true response variable is known only up to an interval in 
which it lies. Features of the package include: power calculations for 
two-group comparisons, computation of Bayesian residuals using 
Multiple Imputation, capability of fitting models for index-kind data 
(e.g., quality of life indexes). Any kind of feedback (questions, 
suggestions, bug-reports, etc.) is more than welcome.


Best,
Dimitris Rizopoulos
