Whether you're hitting the books for a probability or statistics course or hitting the tables at a casino, working out probabilities can be problematic. This book helps you even the odds. The probability distribution of a random variable X tells what the possible values of X are and how probabilities are assigned to those values. Each PD is given by a probability function that generalizes the probabilities of the outcomes. Using this, we can estimate the probability of a particular outcome(discrete) or the chance that it lies within a particular range of values for any given outcome(continuous). For example, the following table defines the discrete distribution for the number of cars per household in California. This is also sometimes referred to as categorical distribution as each possible outcome is treated as a separate category. This is interpreted as the number of failures (other numbers apart from 4) that will occur before we see the third success. There is also a marginal distribution of \(Y\).As you might guess, the marginal p.m.f. Continuous probability distributions are characterized by having an infinite and uncountable range of possible values. This is a book about statistical distributions, their properties, and their application to modelling the dependence of the location, scale, and shape of the distribution of a response variable on explanatory variables. 6.4 - More Examples; Section 2: Discrete Distributions.
