A Rule of Thumb (not only) for Gamblers
Let prize X in a game be a random variable with a cumulating distribution function F, EX] 6 = 0, and Var(X) < 1. In a Gambler's Ruin Problem we consider the probability P F (A; B) of accumulating fortune A before losing the initial fortune B. Suppose our Gambler is to choose between diierent strategies with the same expected values and diierent variances. P F (A; B) is known to depend in genera...
متن کاملA Rule of Thumb for Riffle Shuffling
We study how many riffle shuffles are required to mix n cards if only certain features of the deck are of interest, e.g. suits disregarded or only the colors of interest. For a wide variety of features, the number of shuffles drops from 3 2 log2 n to log2 n. We derive closed formulae and an asymptotic ‘rule of thumb’ formula which is remarkably accurate.

متن کاملA Simple Rule of Thumb for Statistically Significant Correlation
Dennis Walsh, Middle Tennessee State University The correlation between two normal random variables is considered statistically 3 significant if the sample correlation coefficient is sufficiently large or sufficiently small. r We present an easy rule of thumb for detecting statistical significance at the .05 level of significance. Specifically, we will show that if > 2/ , then the correlation i...
