Abstract:

In this paper,we have exactly defined the general formulae for the multivariate  regression chain model and the block regression chain model proposedinpaper [1]and [2].When the random vector in the models does not follow a multivariate normal distribution,regression coefficients of both models are represented in terms of the elements ofthe covariance matrix.Those extend the results of[1]and[2]tothe cases of general distributions.Further we show the relationship between the coefficients of a special block regression chain model and the elements of the covariance matrix.

Key words: Multivariate regression chain model, Partial variance matrix, Reduciblezero pattern
