property PanelEffectsResults.corr_squared_within: float

Within coefficient of determination using squared correlation

Returns
float

Within coefficient of determination

Notes

The within rsquared measures the fit of the dependent purged of entity effects on the exogenous purged of entity effects.

This measure is based on the squared correlation between the entity-wise demeaned dependent variables and their demeaned predictions.

\[Corr[y_{it}-\bar{y}_i, (x_{it}-\bar{x}_i)\hat{\beta}]\]

This measure does not account for weights.
