@ArjunDhiman see update, note also $A^c \cup B^c = (A \cap B)^c$

comment What is $dx/dF(x)$ where $F(.)$ is a continuous, increasing function.
yes, then sounds like you are looking at something like $dF^{-1}(x)/dx$ or a flavor of that...

do you mean $dF(x)/dx$?

$\chi^2$ is the distribution of $X^2$, where $X \sim \mathcal{N}(0,1)$

comment Distribution of e, least squares residuals
Feels like $e^T e$ will be related to $\epsilon^T \epsilon$, which is a linear combination of squares of standard normals, so a linear combination of $\chi^2$ distributions. Does this make sense?

comment Distribution of e, least squares residuals
shouldn't it be a sum of $\chi^2$?
