COGNITIVE POTENTIAL OF THE SELF-DETERMINATION COEFFICIENT OF THE STATISTICAL ANALYSIS

Lyubomir Ivanov

Abstract: The article discusses the possibilities of applying the self-determination coefficient in the process of statistical analysis of dynamics. It outlines how the coefficient is evaluated and how its statistical significance is checked. A total of five strands are available in which the coefficient can be used: As a synthesized indicator of the available regularities in a particular time series; as a potential opportunity to build a linear development model; As a measure of predictability of the time series; As an alternative random order test; As a basis for more accurately assessing the adequacy of built patterns for smoothing the time series. Based on data for three demographic indicators, the application of the coefficient in all five directions is illustrated.
