Probability Density Function From Wolfram Mathworld This probability is given by the integral of a continuous variable's pdf over that range, where the integral is the nonnegative area under the density function between the lowest and greatest values of the range. The red curve represents the standard normal density function with mean. use the sliders to see how normal density functions with other means and standard deviations compare to the standard normal density function. When working with continuous random variables, we describe probability distributions using a probability density function (pdf) rather than a probability mass function.

The normal distribution is implemented in the wolfram language as normaldistribution [mu, sigma]. the so called "standard normal distribution" is given by taking and in a general normal distribution. The distribution function d (x), also called the cumulative distribution function (cdf) or cumulative frequency function, describes the probability that a variate x takes on a value less than or equal to a number x. In one dimension, the gaussian function is the probability density function of the normal distribution, f (x)=1 (sigmasqrt (2pi))e^ ( (x mu)^2 (2sigma^2)), (1) sometimes also called the frequency curve.
