Percentile

Perform sigmoidal Emax model fit using 'Stan' in a formula notation, without writing 'Stan' model code.

#### survParamSim

cran
99.99th

Percentile

Perform survival simulation with parametric survival model generated from 'survreg' function in 'survival' package. In each simulation coefficients are resampled from variance-covariance matrix of parameter estimates to capture uncertainty in model parameters. Prediction intervals of Kaplan-Meier estimates and hazard ratio of treatment effect can be further calculated using simulated survival data.
