## Formulas

### Variables

 Sourceof variation Degreesof freedom Sumsof squares Meansquares F statistic Regression $$rdf$$ $$ssr$$ $$msr$$ $$F_{stat}$$ Error $$edf$$ $$sse$$ $$mse$$ Total $$tdf$$ $$sst$$

$n \rightarrow sample\ size$ $k \rightarrow number\ independent\ variables$ $R^{2} \rightarrow coefficient\ of\ determination$

### 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

$F_{stat} = {msr\over{mse}}$
