So the RSS = SSR = SSE
Now, according to this post in Wikipedia the…

Derivation of SSE(reduced)-SSE(full) = $(C\hat \beta - h)'(C(X'X)^{-1}C)^{-1}(C\hat \beta - h) $
When stating hypothesis in matrix formulation, as H0: $C\hat\beta=h$, $SSE(reduced)-SSE(full)$ can be expressed as:
$$(C\hat \beta - h)'(C(X'X)^{-1}C)^{-1}(C\hat \beta - h) $$
How is this result derived? It looks very weird considering it has no Y…
