panel_between

Perform a Between estimator regression on panel data.

The Between estimator for regression analysis on panel data is focusing on the differences between entities (such as individuals, companies, or countries) over time. By aggregating the data for each entity and analyzing the average outcomes, this method provides insights into the overall impact of explanatory variables (x_columns) on the dependent variable (y_column) across all entities.
