Abstract:
Statistical data in chronological or dynamic series is different from the other data series ordered according to the time variable. This is the importance of studying the chronological series. One can determine the important role of the time factor in social economic phenomena as in other areas. In fact, in the economic and social life much of the data subject to research is constituted as chronological series. An important component of the chronological series along with trend, random and cyclical oscillations are seasonal oscillations. The article presents the methods by which seasonal oscillations can be analyzed.
