Represented this way, $\bf Y$ & $\boldsymbol\varepsilon$ are vectors of duration $N$, and $\boldsymbol\beta$ is a vector of duration $p+one$. $\bf X$ has become a matrix with $N$ rows and $(p+1)$ columns. within a prototypical regression you've got $p$ continual $X$ variables and also the intercept. As a result, your $\bf X$ matrix is made up of a
