Carlo experiments we examine the actual size of various asymptotic procedures for testing the poolability hypothesis, i …

of these homogeneity tests are necessary conditions (or maintained assumptions) for poolability of the data. Thus …

We show how to easily implement a Roy-Zellner test for poolability in STATA and we offer an application to the Grunfeld …
