Abstract
The multivariate location-scale model with a family of
spherically contoured errors is considered for both realized and
future responses.
The predictive distributions of the
future location vector (FLV) and future residual sum of squares
(FRSS) for the future responses are obtained. Conditional on the
realized responses, the FLV follows a multivariate Student-t
distribution whose shape parameter depends on the sample size and
the dimension of the location parameters of the model, and the
FRSS follows a scaled beta distribution. The results obtained by
both the classical and Bayesian methods under uniform prior are
identical. This paper generalizes the results for location-scale
models with multivariate normal and Student-t models to a wider
family of spherically/ellipticcally contoured models.
