\[ n \rightarrow sample\ size \] \[ k \rightarrow number\ independent\ variables \] \[ R^{2} \rightarrow coefficient\ of\ determination \]
Regression Degrees of Freedom
\[rdf = k\] \[rdf = tdf - edf\] \[rdf = {ssr\over msr}\]
Error Degrees of Freedom
\[edf = n - k - 1\] \[edf = tdf - rdf\] \[edf = {sse\over mse}\]
Total Degrees of Freedom
\[tdf = n - 1\] \[tdf = rdf + edf\]
Regression Sum of Squares
\[ssr = msr \times rdf\] \[ssr = sst - sse\] \[ssr = R^{2} \times sst\]
Error Sum of Squares
\[sse = edf \times mse\] \[sse = sst - ssr\] \[sse = sst \times (1 - R^{2})\]
Total Sum of Squares
\[sst = ssr + sse\] \[sst = {sse\over{(1 - R^{2})}}\] \[sst = {ssr\over{R^{2}}}\]
Regression Mean Squares
\[msr = {ssr\over{rdf}} \] \[msr = F_{stat} \times mse \]
Error Mean Squares
\[mse = {sse\over{edf}} \] \[mse = {msr\over{F_{stat}}} \]
F-Statistic
\[F_{stat} = {msr\over{mse}} \]
