"WebUsually, we consider that if p-value < 0.05 for a certain variable then it is significant and has some relationship with your predictor. In this case, sex with p-value 0.0101 and income with 1.79e-05 are both below 0.05 and so therefore are significant. The p-value can be obtained by looking the t-value (third column) up in a t-distribution table . " - Shows variable predictor

WebFor backward selection using the AIC, suppose we have 3 variables (var1, var2, var3) and the AIC of this model is AIC*. If excluding any one of these three variables would not end up with a AIC which is significantly lower than AIC* (in terms of ch-square distribution with df=1), then we would say these three variables are the final results. WebThe figure below shows four hypothetical scenarios in which one continuous variable is plotted along the X-axis and the other along the Y-axis.
