 Sep25 comment Let $b_n$ decrease monotonically to zero, prove $\sum b_nz^n$ converges for $|z|\leq 1$ and $z\neq 1$ @njguliyev oh nice, that does it right there, thanks. Sep25 asked Let $b_n$ decrease monotonically to zero, prove $\sum b_nz^n$ converges for $|z|\leq 1$ and $z\neq 1$ Sep21 comment Prove that if the Hessian of $f$ is positive definite at $a$, then the function attains a minimum at $a$ oh shoot you're right, ok that makes sense. Sep21 comment Prove that if the Hessian of $f$ is positive definite at $a$, then the function attains a minimum at $a$ not off the top of my head no, we've just been using this condition without explanation in a numerical optimization class. Sep21 comment Prove that if the Hessian of $f$ is positive definite at $a$, then the function attains a minimum at $a$ Are you sure? The wikipedia article doesn't mention it. Sep21 revised Prove that if the Hessian of $f$ is positive definite at $a$, then the function attains a minimum at $a$ added 27 characters in body Sep21 comment Prove that if the Hessian of $f$ is positive definite at $a$, then the function attains a minimum at $a$ I don't know about other conditions, I'm basing this off of en.wikipedia.org/wiki/… I guess it says the Hessian must be invertible as well. Sep21 comment Prove that if the Hessian of $f$ is positive definite at $a$, then the function attains a minimum at $a$ @JonathanY. I'm having trouble seeing how this shows positive curvature in all directions. Sep21 comment Prove that if the Hessian of $f$ is positive definite at $a$, then the function attains a minimum at $a$ You're right, I guess I should have specified for $n\geq 2$.

Aug14 comment Calculating a probability mass function (sufficient statistic) @AlexR. so you're saying that $T$ is not a random variable taking values in $1,...,n$ depending on which $X_k$ is the smallest, but instead takes the value of $X_{(1)}$?
