Dear all,
I take the log of difference between two standard normal CDFs,
that is
but in most of the cases D=inf. Is there a way to avoid having inf?
Thanks in advance,

Log of zero is -Inf. To avoid that add a small number before taking the log. For example -
D = log(normcdf() - normcdf() + 0.00001)
