Function Documentation

void backward (    )

PSI Exact Simulation. void backward() This is the real kernel simulation of PSI.

void forward (    )

PSI Forward simulation. This simulation technique is based on the same coupling technique than Perfect Simulation, but it returns a not exact sampling of .

int main (  int    argc, char **    argv )

PSI Main Program. Different interface menus of PSI.

void mcmc (    )

Classical Monte Carlo Simulation. We give an arbitrary initial state and a steps number for Monte Carlo simulation. This steps number correspond to the burn-in time wished by the user.

void norm (    )

Graphical analyze. void norm() We obtain graphics of stationary distribution estimation (or functional) and iterations number observation.

void precomputation (    )

Precomputation of PSI.

void simu (    )

PSI Simulation Menu. Backward simulation is based on CFTP algorithm and return an exact sampling of , whereas Monte Carlo simulation return a pseudo sampling of .

void tool (    )

PSI tools.

void trajectory (    )

Give a forward trajectory. User gives initial state and length of trajectory. Results can be seen in corresponding '.traj' file.
