Hello!

I am trying to conduct a multilevel LCA where people are nested within 10 or more cities. I am identifying the city variable as nominal. I keep getting the following error:

*** ERROR in VARIABLE command
Unknown variable in NOMINAL option:
city

Here are the variable, analysis, and model parts of the program:

VARIABLE:
NAMES ARE id syeptot (15 variables) coneptot
(15 more variables) infeptot (15 more variabls) cnseptot
(14 final variables notests ptime city testres ;

Missing are . ;

USEVARIABLES ARE syeptot coneptot infeptot cnseptot city;
NOMINAL = city;

CLASSES = c(2);
CLUSTER = city;

ANALYSIS:
TYPE IS MIXTURE COMPLEX;
ALGORITHM=INTEGRATION;

STARTS=100;
LOGHIGH = +15;
LOGLOW = -15;
UCELLSIZE = 0.01;
ESTIMATOR IS MLR;
LOGCRITERION = 0.0000001;
ITERATIONS = 1000;
CONVERGENCE = 0.000001;
MITERATIONS = 500;
MCONVERGENCE = 0.000001;
MIXC = CONVERGENCE;
MCCONVERGENCE = 0.000001;
MIXU = CONVERGENCE;
MUCONVERGENCE = 0.000001;

MODEL:
%OVERALL%
syeptot WITH coneptot-cnseptot;
coneptot WITH infeptot cnseptot;
infeptot WITH cnseptot;

Could you please advise?

Many thanks,

Danie

Try taking your city variable off the Nominal list. The Nominal and other variable declarations are only for dependent variables used in the Model command.
