Hierarchical Regression F‑Value Calculator
Compute the F‑statistic for the incremental change in \( R^2 \) between two nested regression models:
$$ F=\frac{(R^2_{\text{full}}-R^2_{\text{base}})/(k_{\text{full}}-k_{\text{base}})}{(1-R^2_{\text{full}})/(n-k_{\text{full}}-1)}. $$

This tool computes the F-statistic and corresponding p-value for a one-way ANOVA. Enter the Sum of Squares Between (SSB), Degrees of Freedom Between (dfB), Sum of Squares Within (SSW), and Degrees of Freedom Within (dfW) to determine the F-value and p-value. For high-stakes decisions, verify results with professional statistical software or consult a statistician.…
