 The Gamma distribution formula_33 is NEF-QVF because the mean of the Gamma distribution is formula_34 and the variance of the Gamma distribution is formula_35, so the variance is a quadratic function of the mean.4.The binomial distribution formula_36 is NEF-QVF because the mean is formula_37 and the variance is formula_38 which can be written in terms of the mean as
formula_39
