Im working with survey data [pweights].  I used the svy : heckman command for
correcting selectivity but i dont know if rho is statistically different from zero. 
I know LR test cannot be applied when using weights but i don't know how to
implement any other test (Wald Test for example).
Thanks for you attention,
Liliana Olarte
