in the work, based on the results of previous studies of the program Fractan, described developed a VBA computer program for fractal time series analysis of measurement results. The method of estimation of accuracy of the offered program is developed. The results of the study of the developed computer program showed high accuracy of the algorithms for calculating the Hurst index incorporated in this program
