Hello! I want to make a regresion by maximum likelihood estimation, the
function has included a join cumulative distribution fuction.

so, i give to program the follow instruction:

binorm(h,k,p) as in the manual of stata.

My problem is that h = infinity (Math) and I do not know how i can give
this instruction.

Could anyone help me?
A possible fix is to use the "magic number" 1e300 (ten to the power of 300), commonly used in the Stata community as a proxy for infinity. For instance, you might type

. disp binorm(1e300,1e300,0.5)
1

. disp binorm(1e300,0,0.5)
.5


I hope this helps.

Roger
