I am a third year Ph.D. student in Statistics at Ohio State University. I'm slowly but surely trying to learn R and C++.

 7 What distribution function $F$ is such that if $\{ X_i \}_{i=1}^{N} \sim F$, then $X_1 + … + X_N$ is most nearly exponential? 5 What formula is used for standard deviation in R? 3 Statistical hypothesis testing, one-sided t-test 3 Will AIC and R-square rank models similarly if the number of variables is equal? 3 The exact distribution of Wilcoxon rank-sum statistic U
