WebSince our calculated t-value of 6.294 is greater than the critical value of 2.365, the p-value is less than 0.001, which means that the probability of observing a t-statistic as extreme or more extreme than 6.294 under the null hypothesis is less than 0.001. Therefore, we can conclude that the coefficient of the predictor variable x1 is ... WebJul 2, 2016 · It is demonstrated here that standardized regression coefficients greater than one can legitimately occur. Furthermore, the relationship between the occurrence of such coefficients and the extent of multicollinearity present among the set of predictor variables in an equation is examined. northeastern lighting
