[ADMB Users] difference between ADMB-RE and R/mgcv in SEs for smoother coefficients in a GAM fitted by maximum likelihood

[dave fournier]

OK that helped.  Around line 72 in getbigs.cpp I beleive the sign is wrong.
It should be


    uhat_prime=-minv*Dux;

This corresponds to   uhat'(x) = - (L_uu)^{-1} L_xu
