I am trying to update some old model results from Mplus 5.1 for a manuscript. When I ran the same input file in the Mplus 7.1, I got the below warning:
"A latent between-level variable is created for an x-variable but not referred to on the between level. Please check that this is what is intended. If this is not intended, specify the variable as a within variable. Problem with: PVIQUAD"
The old syntax originally ran in Mplus 5.1 is pasted below. I was wondering if there is a way to reproduce the old results in Mplus 7.1? Thanks!
WEIGHT IS STUWT; BWEIGHT IS W_FSCHWT; WTSCALE = CLUSTER;
USEVARIABLES ARE Zkst16 ZPVSCIE pviquad; cluster is SCHOOLID; missing are all (999);
You need to mention pviquad in the between level as a covariate or put it on the WITHIN list.

Thank you. I just tried putting pviquad at within level (within is pviquad;) - because it was not estimated at between level previously. The model ran, and had the same number of free parameters as in the above script from v5.1, but it still doesn't seem to give the same results as from v5.1.
