predboot package

Optimism-corrected predictive accuracy measures for multivariable prediction models

A R package for computations of optimism-corrected predictive accuracy measures for multivariable prediction models:

• Calculating optimism-corrected C-statistics by bootstrap correction methods (Harrell, 0.632, and 0.632+ methods)
• Constructiong multivariable prediction models by ML, ridge, and lasso regressions
• Computing bootstrap-based optimism-corrected confidence intervals for the predictive accuracy measures
