WebbOften, probability mass functions are plotted as column charts. For example, the following plot shows the pmf of the Poisson distribution , which is We set the parameter and plot the values of the pmf only for arguments smaller than (note that the support of the distribution is , i.e., the set of all non-negative integers, but the values of become very small for ).

A probability mass function of a discrete random variable $${\displaystyle X}$$ can be seen as a special case of two more general measure theoretic constructions: the distribution of $${\displaystyle X}$$ and the probability density function of $${\displaystyle X}$$ with respect to the counting measure. We … Visa mer 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 … Visa mer Two or more discrete random variables have a joint probability mass function, which gives the probability of each possible combination of realizations for the random variables.
