Can I perform adjusted F tests for a subset of parameters without doing this by hand as suggested in the ChiSq area of the Mplus home page?

model
y=age1 age2 age3 female;

I want to test age1 age2 age3 with a 3 df test (adjusted F if possible). How to do this with Mplus 5.2?

You can use MODEL TEST to perform a Wald test. See the user's guide for further information.

Thanks very much. Will this option do the complex sample adjustments if I use type=complex and use the correct stratification/cluster/weights? Pat

MODEL TEST will use the same options used in model estimation.

Thanks, I've got another question:
can I use multiple model test statments within one program like below ?

model
y=ed1 (p1)
ed2 (p2)
age1 (p3)
age2 (p4)
;

model test:
p1=0 ; p2=0 ; *test education with 2df ;
model test:
p3=0 ; p4=0 ; *test age with 2 df ;

No, the MODEL TEST commands will be combined. You need to do them separately.
