Re: [R] It seams that fast99 function (sensitivity package) does not work out for norm distribution.

It is the problem of norm distribution. You know that 0 and 1are coresponding to -inf and inf by qnorm function, which is no physical meaning. That is why NA occured in sensitivity index. The author recommended either using truncated norm distribution or tricky number of sampling to avoid the 0
