This MATLAB function returns the probability density function (pdf) of the standard normal distribution, evaluated at the values in x.
This MATLAB function returns the probability density function (pdf) of the standard lognormal distribution, evaluated at the values in x.
(MatLab eda11_03) where t is a vector of t values. 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...
