Dearest Mplus,

I've never been able to get the list function to work when constraining a set of parameters + think it's about time I worked out why.

This is my current model. I want to constrain factor loadings across genders.

Model:
%overall%
f by a_happ* c_reli e_exci b_bore d_hope;
f@1;
[f@0];

model gender:
%gender#1%
f by a_happ* c_reli e_exci b_bore d_hope (1-5);
f@1 (eqvar) ;
[f] ;
%gender#2%
f by a_happ* c_reli e_exci b_bore d_hope (1-5);
f@1 (eqvar) ;
[f] ;

However I am given the error:
" There are more equality labels given than there are parameters.
Some equality labels will not be used.
Equality: 1-5"

and I end up with a model in which ALL loadings are constrained to the same value.

I've tried in the past with a variety of models + have had no success :-(

Any ideas gratefully recieved


thanks, Jon

The list of labels can be used only with a list of parameters, for example,

f by a_happ* (1)
c_reli - d_hope (2-5);

if the variables are in order.

I don't think a_happ can be included in the list because of the asterisk.

Ah thanks Linda, that could well be it.
The variables are ordered in my datafile
alphabetically but are ordered in the model by positive/negative valence

i'll give that a go
