(It is possible that adjusted R-squared is negative if the model is too complex for the sample size and/or the independent variables have too little predictive value, and some software just …
WebSep 29, 2024 · The core idea of adjusted R 2, is to replace the biased estimators with their unbiased counterparts. The unbiased estimates are ˜σ2 ϵ = SSR / (N − p − 1) and ˜σ2 Y = SST / (N − 1) This leads to the adjusted R 2, which is called Ezekiel estimator in the statistical literature: Ezekiel: ˆρ2 E(R2) = 1 − N − 1 N − p − 1(1 − R2).
