Fitting distributions consists in finding a mathematical function which represents in a good way a statistical

variable. A statistician often is facing with this problem: he has some observations of a quantitative character

x1, x2,… xn and he wishes to test if those observations, being a sample of an unknown population, belong

from a population with a pdf (probability density function) f(x,q), where q is a vector of parameters to

estimate with available data.
