Hi,
I don't know the answers to all of your questions, but I'll give a shot at two of them
> What is the athrho for?
As far as I know the athrho is used in the maximization process. rho is usually calculated as follows
rho = [exp(2*athrho)-1]/[exp(2*atrho)+1]
This means that athrho can take on any value from minus infinity to infinity and rho will still have a value between -1 and 1.
> Particularly, I am concerned whether "binorm" command is appropriate in calculating the bivariate normal distribution with the correlation term rho.
-binorm- (according to the reference guide, see functions -> probability distributions and densitiy functions)
description: returns the joint cumulative distribution \Phi(h, k, rho) of bivariate normal, with correlation rho; cumulative over (-infty, h]x(-infty,k];
Good luck!
