Weball rely on several assumptions, e.g., the conditions for the Gauss Markov theorem and usually Gaussianity of the errors. Methods for checking and validating these … Webassumption (Bollen, 1989). Here, strict lower triangularity is de ned as a lower triangular structure with the diagonal consisting entirely of zeros. Errors e l follow non-Gaussian distributions with zero mean and non-zero variance, and are jointly independent. This model without assuming non-Gaussianity distribution is called a fully recursive ...
