In Section 2.4.2 we are interested in determining whether a given dataset follows a specific statistical distribution. Here, a short introduction into statistical tests based on the Empirical Distribution Function (EDF) is given. Lets consider a random variable X. The propability that X will give a value less than or equal to the value x is computed by evaluating the Cumulative Distribution Function (CDF) at x. Assuming that X follows a distribution given by the Probability Distribution Function (PDF) f X (t) the probability of X can be computed giving a value less than or equal to x, that is evaluate the CDF, by integration of the PDF as follows:
