 Feb13 reviewed No Action Needed Where is the maximum bias and variance in a histogram as non-parametric density estimator? Feb13 reviewed No Action Needed If $p:E\to X$ is a covering map ($X$ connected and locally arcwise connected) then is $E$ locally connected? Feb13 reviewed No Action Needed Proof with Dirac delta function Feb12 reviewed No Action Needed For an element, Prove there exist finitely many polynomials in a set Y such that u is a 0 of them iff u is a 0 of all polynomials in Y Feb12 reviewed No Action Needed Find a vector parametric equation $\vec r(t)$ for the line through the points $P\equiv(1,0,−4)$ and$Q\equiv(3,−3,1)$ Feb12 reviewed No Action Needed Mixed partial derivative product rule Feb11 comment The function given by the Rao-Blackwell theorem is a statistic No, $\mathbb E_\theta[V_n|T_n=t]=\sum_{\lbrace x:T_n(x)=t\rbrace}\mathbb P_\theta(X=x|T_n=t)V_n(x)$ follows by definition of expectation. We sum over all possibilities of $x$ given $T_n=t$. It is not true in general that $\mathbb E_\theta[V_n|T_n=t]=\sum_{\lbrace x:T_n(x)=t\rbrace}\mathbb P_\theta(V_n=V_n(x)|T_n=t)V_n(x)$ Feb11 reviewed No Action Needed Solution techniques for optimization problems Feb11 reviewed No Action Needed Probability no two pairs are grouped together twice in a row?

Feb4 reviewed No Action Needed What is a proper way to solve this inequation?
