We construct tests for normality in the Azzalini and Capitanio skew-t and linear skew-t classes of distributions. We also provide an explanation for the presence of the inflection point at zero in the skew-normal log-likelihood when it is obtained from a skew-t log-likelihood with degrees of freedom tending to infinity.

Abstract
We construct tests for normality in the Azzalini and Capitanio skew-t and linear skew-t classes of distributions. We also provide an explanation for the presence of the inflection point at zero in the skew-normal log-likelihood when it is obtained from a skew-t log-likelihood with degrees of freedom tending to infinity.
