WebThe coefficient of determination is useful because it gives the proportion of the variance (fluctuation) of one variable that is associated with fluctuation in the other variable. ... If two variables had a correlation of plus or minus 1.00, the corresponding coefficient of determination would equal +1.00. This would mean that 100% of the ... WebtStat — t -statistic for each coefficient to test the null hypothesis that the corresponding coefficient is zero against the alternative that it is different from zero, given the other predictors in the model. Note that tStat = Estimate/SE. For example, the t -statistic for the intercept is 47.977/3.8785 = 12.37.
