singular value decomposition

Postby ilovefortran » Mon Feb 21, 2011 6:19 pm

I use GAUSS program. I use svd1 first and the program was aborted with error message: "Not all the singular values can be computed." Then I replace svd1 with lapsvdcusv. The program keeps running with warning message "lapsvd1: illegal value in argument". Would you be able to tell me what this means and what could potentially cause this problem? I am concerned that because of this error message, what I get out of optimization is garbage. Or could I safely ignore this warning and trust the results?
It is unlikely due to coding error because I cross checked with Dynare and they gave the same likelihood value at the initial guess.

I really appreciate for your help.
Many thanks
Kind Regards
