rms

Regression Modeling Strategies

Current Goals

  • Implement estimation and prediction methods for the Bayesian partial proportional odds model blrm function

Web Sites

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
