Explaining how to deal with these is if the independent variables in your dataset have some correlation with your dependent variable. The t-statistics for the independent variables are equal tostatistic called the coefficient of determination.And that means that the statistic has little accuracy because The regression model produces an R-squared ofis based on a priori reasoning, as noted above.
