Webwe see that the cumulative distribution function F ( x) must be defined over four intervals — for x ≤ − 1, when − 1 < x ≤ 0, for 0 < x < 1, and for x ≥ 1. The definition of F ( x) for x ≤ − 1 is easy. Since no probability accumulates over that interval, F ( x) = 0 for x ≤ − 1. Similarly, the definition of F ( x) for x ≥ 1 is easy. WebDec 1, 2024 · Probability mass and density functions are used to describe discrete and continuous probability distributions, respectively. This allows us to determine the probability of an observation being exactly equal to a target value (discrete) or within a set range around our target value (continuous).

WebGeometric Distribution. Assume Bernoulli trials — that is, (1) there are two possible outcomes, (2) the trials are independent, and (3) p, the probability of success, remains the same from trial to trial. Let X denote the number of trials until the first success. Then, the probability mass function of X is: f ( x) = P ( X = x) = ( 1 − p) x ... WebIn probability theory and statistics, the Poisson distribution is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space if these events occur with a known constant mean rate and independently of the time since the last event.
