In probability and statistics, the Dirichlet distribution (after Peter Gustav Lejeune Dirichlet), often denoted (), is a family of continuous multivariate probability distributions parameterized by a vector of positive reals.It is a multivariate generalization of the beta distribution, hence its alternative name of multivariate beta distribution (MBD). to find the mean, let's use it to find the variance as well. Deviation for above example. Standard Deviation is square root of variance. This distribution for a = 0, b = 1 and c = 0.5the mode (i.e., the peak) is exactly in the middle of the intervalcorresponds to the distribution of the mean of two standard uniform variables, that is, the distribution of X = (X 1 + X 2) / 2, where X 1, X 2 are two independent random variables with standard uniform distribution in [0, 1]. Let (,) denote a p-variate normal distribution with location and known covariance.Let , , (,) be n independent identically distributed (iid) random variables, which may be represented as column vectors of real numbers.

Microsofts Activision Blizzard deal is key to the companys mobile gaming efforts. In 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. In probability theory and statistics, the Poisson binomial distribution is the discrete probability distribution of a sum of independent Bernoulli trials that are not necessarily identically distributed. The expected value of a random variable with a finite number of where denotes the sum over the variable's possible values.

(If all values in a nonempty dataset are equal, the three means are always equal to one In standard cases this will be a well-known result. It is a measure of the extent to which data varies from the mean. The central limit theorem states that the sum of a number of independent and identically distributed random variables with finite variances will tend to a normal distribution as the number of variables grows. The choice of base for , the logarithm, varies for different applications.Base 2 gives the unit of bits (or "shannons"), while base e gives "natural units" nat, and base 10 gives units of "dits", "bans", or "hartleys".An equivalent definition of entropy is the expected value of the self-information of a variable. mile (mi) milli-milligram (mg) milliliter (mL) millimeter (mm) million Uncertainty about the probability of success.
