The exponentially modified normal distribution is another 3-parameter distribution that is a generalization of the normal distribution to skewed cases. The skew normal still has a normal-like tail in the direction of the skew, with a shorter tail in the other direction; that is, its density is asymptotically proportional to for some positive . Thus, in terms of the seven states of randomness, it shows "proper mild randomness". In contrast, the exponentially modified normal has an expo… Webb3 jan. 2024 · It assumes the response variable is conditionally distributed Gaussian (normal) but doesn't assume anything about the covariates or predictor variables (that said, transforming the covariates so that it's not just a few extreme values dominating the estimated effect often makes sense.)
