constraint in MVML model
Posted: Mon Oct 19, 2020 8:19 pm
H Chris, George and all listers,
I am playing constraint for MVML model but the following code not working.
use "http://www.bristol.ac.uk/cmm/media/runmlwin/gcsemv1.dta", clear
constraint drop _all
constraint define 1 [RP1]var(cons_1) = var(cons_2) // equal level 1 variance for both Y variable
constraint define 2 _b(female_1)=_b(female_2) // equal coefficient across equation
runmlwin (written cons female, eq(1)) (csework cons female, eq(2)), ///
level2(school: (cons, eq(1)) (cons, eq(2))) ///
level1(student: (cons, eq(1)) (cons, eq(2))) constraint 1/2 nopause
option constraint incorrectly specified
I know how to set parameters equal if using MLwiN test and interval. any help here please? thanks.
