WebMar 30, 2024 · In this article, we introduce a new community-contributed command, xthst, to test for slope heterogeneity in panels with many observations over cross-sectional units and time periods. The command implements such a test, the delta test (Pesaran and Yamagata, 2008, Journal of Econometrics 142: 50–93). Under its null, slope coefficients are ... WebDec 26, 2013 · A “poolability” test is very important for dealing with panel data. The null hypothesis is that the slope for independent variables (other than group and time) are constant across groups (or time). If the null hypothesis is rejected, the multilevel model (hierarchical regression model is needed).
