“…followed by using Pearson nomograms [27] to determine the desired distribution function. However, many years of experience in the use of nomograms by the authors [27] for modeling complex organizational and technical systems shows that in the absolute majority of cases, the solution converges to a type III Pearson distribution, i.e., approximation of the real distribution function by an incomplete gamma function, which is consistent with [28,29] and is confirmed by system studies [8,30]. In this case, the parameters of the shape and scale of the gamma distribution are determined as…”
