A class of power series skew normal distributions is introduced by generalizing the geometric
skew normal distribution of Kundu [Sankhyˉa B, 76, 2014, 167-189]. Various mathematical
properties are derived and estimation addressed by the method of maximum likelihood. The
data application of Kundu [Sankhyˉa B, 76, 2014, 167-189] is revisited and the proposed class
is shown to provide a better fit.
