R Squared Calculator (Coefficient Of Determination)

R Squared Calculator (Coefficient Of Determination): a planned Super Calculator tool. Covers observed and predicted values. Stub page. Not published yet.

R Squared Calculator (Coefficient Of Determination) is a planned calculator in the mathematics section of Super Calculator, covering statistics and probability.

What this calculator will compute

Inputs: observed and predicted values, or SS residual and SS total, or r, n and number of predictors k.

Outputs: R squared, adjusted R squared and percentage variance explained (%).

Formula, recorded as scope and not yet verified against a primary source: R squared = 1 - SS_res / SS_tot. Adjusted R squared = 1 - (1 - R2) * (n - 1) / (n - k - 1), which penalizes added predictors and can fall when a useless predictor is added.
