It is a common practice to preferover to assess the explainability lonear of a statistical regression model among social scientists, especially for one having more than one what is r2 linear correlation coefficient variables. However, this preference is not advantageous at all times because the usage of may end whwt in negative coefficients making them non-interpretable.
