We can also use our regression technique to test for a significant relationship between two variables. Regression to the mean is due to random variance, or chance, which affects the sample. Thus, in general, this example of a research using multiple regression analysis streamlines solutions and focuses on those influential factors that must be given attention. The term âhysterical puerilismâ is sometimes applied to cases of temporary infantile behavior resulting from prolonged combat or other extreme stresses.The most striking and pathological examples of regression, however, are found in cases of severe personality disorganization.
