Laszlo Sandor <[email protected]> points out an inconsistency in the
documentation for -moptimize()-:

Laszlo is correct. The description for -moptimize_init_eq_coefs()- should be
moptimize_init_eq_coefs(M, i, b0) sets the initial values of the
coefficients for the ith parameter to be b0: 1 x (ki+ci). The default
is (0, 0, ..., 0).
Here 'ci' is 1 if equation 'i' contains an intercept, and 0 otherwise.
We will fix the online help in a future ado-file update.
