The Seasonal Adjustment Research Appraisal committee was created in Italy to evaluate procedures for seasonal adjustment of economic series. Because the TRAMO-SEATS programs were one of the main procedures considered, the committee sent a selection of 11 series of interest to be analysed. This...

This paper derives exact expressions for the statistical curvature and related geometric quantities in the first order autoregressive models.

To solve an easy-to-understand real world problem, we invite the reader to travel through many useful concepts related to the important models provided by the compound normal distributions

The weekend effect is an empirical enomaly that has attracted substantial attention. Following the work of Connoly (1989) it is necessary to revisit previous empirical work. In this paper we examine the weekend effect in Malaysia over the period 1986-1993.

Recent tests using long data series find evidence in favor of long-run PPP (by rejecting either the null hypothesis of unit roots in real exchange rates and relative prices.)

In this paper we examine educational data whch has a cross-classified structure. A cross-classified value-added multilevel model is proposed for these data and the problem of estimation are discussed in relation to the probllem of an endogenous regressor.

We establish the relationships between certain Bayesian and classical approaches to instrumental variable regression. We determine the form of priors that lead to posteriors for structural parameters that have similar properties as classical 2SLS and LIML and in doing so provide some new insight...
