Bernoulli distribution X - William & Mary

Geometric distribution (from X - William & Mary

the geometric distribution with p =1/36 would be an appropriate model for the number of rolls of a pair of fair dice prior to rolling the first double six. The ge ometric distribution is the only discrete distribution with the memoryless property. The only continuous distribution with the memoryless property is the exponential distribution.

This cumulative distribution function can be recognized as that of an exponential random variable with parameter Pn i=1λi. APPL illustration: The APPL statements to find the probability density function of the minimum of an exponential(λ1) random variable and an exponential(λ2) random variable are: X1 := ExponentialRV(lambda1);

Standard uniform distribution (from http://www.math.wm.edu ...

The standard uniform distribution is central to random variate generation. The probability density function is illustrated below. 0 1 0 1 x f(x) The cumulative distribution function on the support of X is F(x)=P(X ≤x)=x 0 <x <1. The survivor function on the support of X is S(x)=P(X ≥x)=1−x 0 <x <1.

Discrete uniform distribution (from X - William & Mary

The shorthand X ∼ discrete uniform(a,b)is used to indicate that the random variable X has the discrete uniform distribution with integer parameters a and b, where a <b. A discrete uniform random variable X with parameters a and b has probability mass function f(x)= 1 b−a+1

Reading 14a: Beta Distributions - MIT OpenCourseWare

18.05 class 14, Beta Distributions, Spring 2014 3. Summary: If the probability of heads is , the number of heads in n+ mtosses follows a binomial(n+ m; ) distribution. We have seen that if the prior on is a beta distribution then so is the posterior; only the parameters a, bof the beta distribution change! We

Beta(s+ ;n s+ ), so this Beta distribution is the posterior distribution of P. In the previous example, the parametric form for the prior was (cleverly) chosen so that the posterior would be of the same form|they were both Beta distributions. This type of prior is called a conjugate prior for P in the Bernoulli model. Use of a conjugate prior

BETA REGRESSION FOR MODELLING RATES AND …

“Beta distributions are very versatile and a variety of uncertanties can be usefully modelled by them. This flexibility encourages its empirical use in a wide range of ap-plications” (Johnson, Kotz and Balakrishnan, 1995, p. 235). Several applications of the beta distribution are discussed by Bury (1999) and by Johnson, Kotz and Balakrish-
