Pooled ordinary least squares regression
WebApr 1, 2024 · There are three types of regression in the panel data analysis, namely Ordinary Least Square, Fixed Effect model, and Random Effect model. The statistical test aimed to choose among the three best alternative models to be used in this study. The Chow test chose between the Ordinary Least Square model and the Fixed Effect model.
