CHOCOTEA POCA, Omar. An introduction to the normal-skew linear regression model. Part 1: Theory, direct parameterization. Revista Varianza [online]. 2022, n.20, pp. 20-25. ISSN 9876-6789.

Abstract In the spectrum of elliptic-asymmetric distributions is the skew-normal distribution, which has the normal distribution as a particular case. The main objective ofthis work is to present the linear regression model with random error variable with skew-normal distribution. This work is divided into three parts. In this part, the basic theoretical aspects associated with direct parameterization are reviewed. In Part 2, the basic theoretical aspects associated with centeredparameterization are reviewed. And in Part 3, the illustration is done with a real data set
