The normal inverse gaussian distribution is a flexible four parameter distribution which often gives
a good fit to the null log similarity scores when these scores are on a scale of 0 to 1. Other than
standardization, this function assumes that if the user wants the scores to be transformed, they've
transformed them. This routine calls the fit.NIGuv
function from the ghyp package.
