WebThis video discusses about poolability test in RStudio. WebDifferent shelf life estimates may be derived using different hierarchical pooling test orderings. On the other hand, setting the hierarchical ordering can be subjective and controversial. The stepwise modeling based on F-tests using type III sum of squares for model determination and factor elimination is proposed to eliminate such difficulties.

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.
