[R] Hypothesis testing after optim

[Peter Muhlberger]

Hi folks:  Does anyone know of a way to do (linear) hypothesis tests of
parameters after fitting a maximum-likelihood model w/ optim?  I can't seem
to find anything like a Wald test whose documentation says it applies to
optim output.  

Also, thanks again to everyone who gave me feedback on the robustness of ML
estimation in R!

Peter
