Abstract

The technique of time series analysis over a period of several years is considered. The technique consists in constructing a predictive model based on data from previous periods: constructing a model with an additive component or constructing a model with a multiplicative component. Based on the time series structure, one of these models is selected. The additive model is constructed if the amplitude of seasonal oscillations is approximately constant. In the event that the amplitude of the oscillations is variable (increases or decreases), a multiplicative model is constructed.
