Residual variation. Sum of the squared deviations between the data y-values and the predicted. y-values -- Σ(y-y')2. Removed or explained variation. Initial variation minus residual variation. k2 is the ratio of residual variation to original variation, Σ(y-y')2 / Σ(y-ybar)2. r2 is the ratio of removed variation to original variation. ................
