%description
It provides users with a wide range of tools to simulate, estimate,
analyze, and visualize the dynamics of stochastic differential systems in
both forms Ito and Stratonovich. Statistical analysis with parallel Monte
Carlo and moment equations methods of SDEs <doi:10.18637/jss.v096.i02>.
Enabled many searchers in different domains to use these equations to
modeling practical problems in financial and actuarial modeling and other
areas of application, e.g., modeling and simulate of first passage time
problem in shallow water using the attractive center (Boukhetala K, 1996)
