Regression Modeling Strategies
Regression modeling, testing, estimation, validation,
graphics, prediction, and typesetting by storing enhanced model design
attributes in the fit. 'rms' is a collection of functions that
assist with and streamline modeling. It also contains functions for
binary and ordinal logistic regression models, ordinal models for
continuous Y with a variety of distribution families, and the Buckley-James
multiple regression model for right-censored responses, and implements
penalized maximum likelihood estimation for logistic and ordinary
linear models. 'rms' works with almost any regression model, but it
was especially written to work with binary or ordinal regression
models, Cox regression, accelerated failure time models,
ordinary linear models, the Buckley-James model, generalized least
squares for serially or spatially correlated observations, generalized
linear models, and quantile regression.

Regression Modeling Strategies
Current Goals
- Implement estimation and prediction methods for the Bayesian partial
proportional odds model
blrm
function
Web Sites
- Overall: http://hbiostat.org/R/rms/
- Book: http://hbiostat.org/rms/
- CRAN: http://cran.r-project.org/web/packages/rms/
- Changelog: https://github.com/harrelfe/rms/commits/master/
To Do
- Fix survplot so that explicitly named adjust-to values are still in subtitles. See tests/cph2.s.
- Fix fit.mult.impute to average sigma^2 and then take square root, instead of averaging sigma
- Implement user-added distributions in psm - see https://github.com/harrelfe/rms/issues/41
