Get the empirical win/draw probabilities based on the ability/strength parameters. Instead of calculating from the probability formula given from the model we create a predictive posterior distribution for all pair combinations and calculate the posterior wins/loose/draw The function returns the mean value of win/loose/draw for the player i. To calculate for player j the probability is 1-p_i
get_probabilities(bpc_object, n = 1000)
a bpc object
number of samples to draw from the posterior
a list with data frame table with the respective probabilities and a matrix with the corresponding posterior
