panel_pooled

Perform a Pooled coefficient estimator regression on panel data.

The Pooled coefficient estimator for regression analysis on panel data is treating the data as a large cross-section without distinguishing between variations across time or entities (such as individuals, companies, or countries). By assuming that the explanatory variables (x_columns) have a uniform effect on the dependent variable (y_column) across all entities and time periods, this method simplifies the analysis and provides a generalized view of the relationships within the data.
