getPrevY.discr

An internal function to compute previous value of
physiological variable Y based on 
discrete-time model

Utilities to estimate parameters of the models with survival functions
induced by stochastic covariates. Miscellaneous functions for data preparation
and simulation are also provided. For more information, see:
