Cohen and Xu (1) claim that random samples of any skewed distributions with four finite moments would give rise to Taylor’s law (TL). In fact, skewed distributions do not necessarily generate data following TL. Some highly skewed distributions can generate random data rejecting the law. Here, I show examples for this using beta, lognormal, and Poisson distributions (the last one is used for comparison).
