WebIn this paper, we consider a nonparametric test for poolability in the model (1.1)-(1.2). Testing for poolability can be traced back to Chow (1960) in econometrics. Since then a large literature has been developed to test structural stability of economic relationships over time or equality of regression functions over individuals. WebThe results of the poolability tests are presented in Table 2. The evidence is mixed. For our data set, three out of the four described tests reject the hypothesis of poolability. Only the …
