This chapter focuses on the regression line and the trend. The determination of the trend is of great practical importance to economic research because the correct knowledge of economic processes is possible only when these processes are interpreted dynamically. Statistical methods of determining trends are part of a branch of mathematical statistics, known as the theory of stochastic processes. Correlation analysis is one of the main research tools used in the theory of stochastic processes. The more the scientific predictions based on the trend line extend into the future, the more valuable they are in practice. The method of determining the parameters of the trend line is a special case of the determination of the regression parameters by the two-point method. |
