Matrix of size pbyk containing in
column $j$, ($j=1, 2, \ldots, k$), the elements on the main
diagonal of shape matrix $\Gamma_j$. The elements of GAM
satisfy the following constraints:
The product of the elements of each column is equal to 1.
The ratio of the elements of each row is not greater than pa.shb.
The ratio of the elements of each column is not greater than
pa.shw. All the columns of matrix GAM are equal if the second
letter of modeltype is E. All the columns of matrix GAM are
equal to 1 if the second letter of modeltype is I. This matrix
can be constructed from routine restrshapepars
