A crossed /nbn/ is a /nbn/ obtained when replacing each node of the
first /nbn/ by the second /nbn/ and vice-versa.
na1/na2 be the node and arc numbers of the two
nbns, the node number of the crossed
nn1*nn2 and its arc number is
The regression coefficients attributed to the crossed
nbn are the
products of the weights (
we1/we2) and the regression
coefficients of the initial
