The program implements the use of χ2 test for determining the distribution law of fluctuations of the signals. Hypotheses about the distribution of this or innogo parameter system, such as expectation, variance, probability density for a given level of significance accepted or refuted, in accordance with the results. The program implements two distributions: the exponential and Rayleigh.
