Chapter 3 Some Univariate Distributions
... We now offer a catalog of some of the more commonly encountered probability distributions (density functions). When we first look at data, in what is sometimes called ‘‘exploratory data analysis,’’ we often want to find a pdf that can act as a probability model for those data. If we can use one of t ...

... equal probability of coming up, mainly because we have no reason to assume otherwise. A way to determine the probability of each face turning up is to roll the die many times and count the frequency with which each side comes up. In principle, every side of a six-sided die has an equal probability o ...

The frequency interpretation applies only to a problem in which there can be, at least in principle, a large number of similar repetitions of a certain process. Many important problems are not of this type. For example, the probability that a particula ...

Let us first make the following trivial observation: the number of Dyck paths of length 2k is equal to the total number of paths from (0, 0) to (2k, 0), minus the number of paths from (0, 0) to (2k, 0) that do hit the negative nu ...
