Hello SAS_Rob, Thank you for your help. I found that solution one month ago and I tried. But it didn't work for one of my variables. It didn't give a p-value. And I am also not clear that what is the difference between this F-test for global significance and the Wald chi-square test used in "type three analysis of effect". I came up with a solution to calculate the combined wald test. After I get the pooled estimation for each level. I used the equation to calculate the chi-square: transposed estimation matrix*inverse matrix of covariance matrix* estimation matrix.

Thank you for your reply. But if I want to study the overall effect of systolic blood pressure (categorical) just like "Type 3 analysis of effect" table in Logistic regression. How can I do it?

I did multiple imputations by using FCS. Now I have 5 imputed data. In my logistic regression, I have a categorical variable "systolic blood pressure" with 4 levels (0, 1, 2, 3) so I want to check the "Type 3 analysis effect" in PROC MIANALYZE to study the overall effect of systolic blood pressure. By using PROC MIANALYZE I only get the effect for each level, but not a global one. I have found someone used the TEST statement like test systolic_0, systolic_1, systolic_2/multi; But I am not sure whether that is the same as the "type 3 analysis of effect"? Thank you for your help!
