Sometimes I wonder why I am still going to school when I can just watch Ben Lambert's video.

the videos are amazing ! This is Quality content ! Great Work !

I think the numerator has to be beta* - beta_true, because the t distribution requires a standard normal distribution in it's numerator.

Question orthogonal to the video content: may I ask what sort of device you use for the screencasts? I plan to do some on-line tutoring and I have a Wacom tablet, but I find it quite difficult to write legibly with the Wacom pencil. It just isn't the same as paper. May I ask what you use? (I've already told you this, by the way, but the videos are fabulous).

Hey someone could explain to me why we don't use the estimation of var(Beta ls) to approximate the distribution of Beta hat instead of creating a t distribution ?

[totochandelier]

if N is great enough, why don t we use a normal N(beta_true, sigma_tilda_square) for inference ?

[danxie]

whats the difference between beta_star and beta_hat?
