PF.m gives the P-value prescribed by the Polya Filter for each link of the network (given the adjacency matrix W and a value for the free parameter a). If the passed value of a is negative, it performs the ML estimation using the get_ML_estimate.m function

get_ML_estimate.m finds the maximum likelihood estimates for the the free parameter a

NOTE: the maximum likelihood estimate are just a possible way to fix the free parameter, other viable options are presented in the paper where the PF is presented :
