getNextY.discr

An internal function to compute the next value of physiological variable Y
based on discrete-time model (Akushevich et. al., 2005)

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:
