so if i have two groups i am using in a group analysis, and i want to know if two variables are statistically the same, i can do the MODEL TEST command, and i know that, my question is can we ask it for more than one comparison in the output and do them individually, like if i want to test if a=b, then if c=d, can i have it test the first one, then test the second? |

All specifications in MODEL TEST are tested simultaneously. You would need to rerun the analysis several times if you want to test single specifications. |

so when we do this test, if the Wald test is significant, and i say p1=p2, if its significant does that mean they are the same or they are different? |
|
|
For the Wald test, H0: p1 = p2; H1: p1 NE p2; If the p-value is less than .05, reject H0 and conclude p1 is not equal to p2. |
