Prima Regional Model

You can play with the demo software of the prima regional model developed for the European Project Prima, with the example of the Cantal case study (a French department).


The package EasyABC enables to launch a series of simulations of a computer code from the R platform, and to retrieve the simulation outputs in an appropriate format for post-processing treatments. Four sequential sampling schemes and three coupled-to-MCMC schemes are implemented.
