In probability theory, a probability density function (PDF), or density of a continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihoo...

y = pdf(name,x,A) returns the probability density function (pdf) for the one-parameter distribution family specified by name and the distribution parameter A, evaluated at the values in x. y = pdf(name,x,A,B) returns the pdf for the two-parameter distribution family specified by name an...
Probability density function 4 is also new and is called the Fisher-Snedecor F-probability density function. It is the ratio of the sum of squares of two different sets of random variables. Its functional form cannot be written in terms of elementary functions and is omitted here. Its mean ...
