This chapter discusses the transformation of curvilinear into linear regression. Substantial simplifications in the computation are achieved by the application of the two-point method to the determination of the regression parameters. For the approxi

This chapter focuses on regression and correlation. One of the basic elements of the learning process is the scientific experiment. One of the objectives of an experiment is to establish a causal relation between the phenomenon studied and other phen

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
