      When we refer to these univariate distributions in a multivariate context, we shall call them the marginal probability functions of X and Y. This name comes from the fact that when the addition in (3.3) or (3.4) is performed upon a bivariate distribution p(x;y) written in tabular form, the results are most naturally written in the margins of ...

      introduces an R package MGLM, short for multivariate response generalized linear models, that expands the current tools for regression analysis of polytomous data. Distribution ļ¬tting, random number generation, regression, and sparse regression are treated in a unifying framework. The algorithm, usage, and implementation details are discussed.

For a multivariate regression (d > 1), Y is a n × d matrix and β is an p × d matrix. Sometimes it will be more convenient to treat the observations Y as an nd-dimensional vector or β as an pd ...
