Hello,   Please, when trying to test if an independent variable is statistically significant, do we have to run the regression for each Independent variable or we have to run a regression with all the Independent variables at once?   Thanks a lot.   Regards,   lizzy100 ... View more

Hello,   Please, when doing a test of statistical significance judging based on the p-value and intervals, is it possible to get difference results. For example, is it possible that judging from the p-values, the independent variables are not statistically significant but judging from the intervals they are statistically significant?   Thanks a lot.   Regards,   lizzy100 ...

Hello,   Please, how can one detect evidence of Multicollinearity through a correlation matrix. How can one remedy the problem of Multicollinearity?   Secondly, how can the test of significance be performed for each coefficient?   Thirdly, based on two confidence intervals gotten through the Multiple Regression equation/ result, how can one know the variable to remove/ variable that is not relevant?   Thanks a lot as I await your feedback.   Regards,   lizzy100 ...

Hello,   Please I want to run a Linear Regression report on SAS Studio in such a way that it will include Tolerance and Variance Inflation in the Parameters Estimates table but I am not yet able to. So I want to know if there are some settings I need to include when trying to run it because currently when I run the Linear Regression on SAS Studio, the Parameters Estimates Table does not include Tolerance and Variance Inflation.   Thanks a lot as I look forward to your feedback.   Regards,   lizzy100 ...
