In probability and statistics, a probability mass function is a function that gives the probability that a discrete random variable is exactly equal to some value. Sometimes it is also known as the discrete density function. The probability mass function is often the primary means of defining a discrete probability distribution, and such functions exist for either scalar or multivariate random var… WebDefinition Let be a continuous random vector formed by the random variables . The joint probability density function of is a function such that for any choice of the intervals. Note that is the probability that the following conditions are simultaneously satisfied: the first entry of the vector belongs to the interval ; the second entry of the ...
