Varying Param Initial conditions

[cel]

I'm estimating some non linear equations and naturally am finding that results are often pretty sensitive to the initial parameter conditions in the param statement.

I wonder therefore if anyone knows how to take all the parameters (or a subset) and simply, say, draw their value from a Normal distribution, estimate the eqn and then save those intial condiitions and some suitable metric (like R^2 or the loglik). Then do this repetedly in a loop.

I guess an important consideration would be an error handler since some of the drawn parameter vector would lead to non convergent solutions.

Thanks in advance!

will create standard normal random numbers in the C vector, which is used for starting values.
