comment Direct computation of $\operatorname{log}(\operatorname{cdf})$ for a normal distribution
I can sum logs and get values like -100000 for example. The problem is that I must be able to distinguish between near 0 and 0 probabilities. If I can not compute log(cdf) directly, I will have to use tricks like considering a cdf inferior to 1.7E- 308 as 1.7E- 308, and then forcing log(cdf) = log(1.7E- 308) = -708 . I wanted to avoid this and compute the real value of log(cdf) directly.

I do this in other part of the code. The problem here is that can not even compute the value of log(cdf).

comment Direct computation of $\operatorname{log}(\operatorname{cdf})$ for a normal distribution
It is a bit of both. I need to add various log. The majority of which are close to 0., but some are under 1.7E- 308, which is the limit of the double type I use to compute the cdf. When I compute the sum I get $-\infty$.

I copied the question directly, I do not have much more clues :).
