03 probability distributions
... called dependent if the occurrence of A affects or is affected by the occurrence of B. • For example, there are four kings in a pack of 52 cards. The event of drawing a king at the first draw and the event of drawing another king at the second draw when the first drawn king is not replaced, are two ...

Nonparametric two-sample tests for increasing convex order
... see Section 2.2 below. In contrast to the classical stochastic order situation these statistics are not distribution-free, so a practical way to obtain critical values is needed. We propose to use the bootstrap; as we will see, this leads to a problem-specific variant that is a consequence of the na ...

Chapter 3: Conditional Probability and Independence
... P(AB), the probability that neither machine breaks down today? If we assume independence, P(AB) = P(A)P(B)—a straightforward calculation. If we do not assume independence, however, we cannot calculate P(AB) unless we form a model for their dependence structure or collect data on their joint performa ...

One aspect of the variance and standard deviation that should make sense is that each measure is constructed from differences of individual values from the mean value. Statisticians often refer to these as deviations about the mean. These deviations about the mean are th ...
