| probability density function |
In mathematics, a probability density function (pdf) serves to represent a probability distribution in terms of integrals. Any function that is everywhere non-negative and whose integral from −∞ to +∞ is equal to 1 is a probability density function. If a probability distribution has density f(x), then intuitively the infinitesimal interval [x, x + dx] has probability f(x) dx. ...

| probability density function |
(Or density function; also called frequency function.) The statistical function that shows how the density of possible observations in a population is distributed. It is the derivative f(x) of the distribution function F(x) of a random variable, if F(x) is differentiable. Geometrically, f(x) is the ordinate of a curve such that f(x)dx yields the probability that the random variable will assume some value within the range dx of x. ...
