Hi, my question is about the significance of the path X->Y1 in the path model X->Y1->Y2->y3. X is categorical and binary; Y1 is continuous. I use ML. The significance level I get for the path X->Y1 is 0.10, two-tailed. However, if I do a simple t-test, I get a significance of 0.15, two-tailed. Why could this be?
