I am a newbie in Mathematica and I aim to use Mathematica mostly for stochastic modeling (to develop and analyze models in evolutionary biology). Note that I am not necessarily a great mathematician yet $\ddot \smile$. I am NOT interested about data analysis and statistics (I usually use R for this purpose) but only about stochastic modeling.
Where can I find good and free ressources (online tutorial, videos, ...) on how to use Mathematica for stochastic modeling?
Note I already asked a bunch of questions on this site that concern stochastic modeling like this one and this one. The two posts already received very good answers but those posts are the kind of questions I amy want to receive answers to by looking at a tutorial.
