  I discuss comments and claims made in Stehlik and Hermann (2015) about skewed
Lambert W x F random variables and the IGMM algorithm. I clarify
misunderstandings about the definition and use of Lambert W x F distributions
and show that most of their empirical results cannot be reproduced. I also
introduce a variant of location-scale Lambert W x F distributions that are
well-defined for random variables X ~ F with non-finite mean and variance.
