It is a common practice to preferover to assess the explainability power of a statistical regression model among social scientists, especially for one having more than one independent variables. However, this preference is not advantageous at all times because the usage of may end whah in negative coefficients making them non-interpretable. A Monte Carlo simulation experiment is used to appraise the behavior of these adjusted versions of for different numbers of independent variables.

It has been found that almost all of the selected adjusted version of produces negative coefficients. Ayabe, C.
