  Stochastic Process Model has many applications in analysis of longitudinal
biodemographic data. Such data contain various physiological variables
(sometimes known as covariates). It also can potentially contain genetic
information available for all or a part of participants. Taking advantage from
both genetic and non-genetic information can provide future insights into a
broad range of processes describing aging-related changes in the organism. In
this paper, we implemented a multi-dimensional Genetic Stochastic Process Model
(GenSPM) in newly developed software tool, R-package stpm, which allows
researchers performing such kind of analysis.
