Using the same notations as in Property 1, and using the general results on the moments of truncated multivariate distributions (see Kan and Robotti, 2017) we may write the following: Using the expressions above and the expressions for and from Equation (3), and after some straightforward but tedious algebra, the simple expressions in Equation (5) result.
