In frequency analysis in hydrology, the streamflow corresponding to a specified exceedance probability p (or return period ) can be computed as

where μ and σ are the mean and standard deviation of the streamflow series, respectively, and is the frequency factor.

Write a function to compute the frequency factor for the normal distribution given the exceedance probability as a vector.
