Stepise combine: combines the stepwise forward and the stepwise backward model.
stepwise.combine(forward_matrix, backward_matrix)The winning sets of parents using a Forward Selection model search. A
matrix with dimension Nn+2 x Nn, rows 1:Nn are the parents (ones and zeros),
rows (Nn+1):(Nn+2) are the LPL and discount factor. forward matrix.
backward_matrix
stepwise_combine_matrix The adjacency network, LPLs and discount factors when the Forward Selection and Backward Elimination model searches are combined.
