Dear Statalisters,
I tried to run a latent class analysis using Stata 10. I have the
following manifest, numeric variables:
id – respondent’s identification
country – identifying respondent’s country of origin
occupationfatherworking – a categorical variable containing
occupational categories that describe the job of respondent’s father
fisced3completed, fisced4completed, fisced5bcompleted,
fisced5acompleted – four dummy variables measuring the level of
education achieved by respondent’s father
wealthindex – an index measuring wealth of household
I expanded my dataset in the following way:
eq classfather: fiscoworking1-fiscoworking533 fisced3completed
fisced4completed fisced5bcompleted fisced5acompleted
wealthindex4dum1-wealthindex4dum4
{fiscoworking1-fiscoworking533 and wealthindex4dum1-wealthindex4dum4
are dummy variables created from occupationfatherworking and
wealthindex}
Then I specified:
eq latentfather: occupationfatherworking fisced3completed
fisced4completed fisced5bcompleted fisced5acompleted wealthindex4cats
and – to get the full independence model – I run:
gllamm classfather, i(id country1) eq(classfather) geq(latentfather)
nrf(533) ip(f) nip(1) adapt
To which Stata answered:
variable classfather not found
r(111);
Could anyone point me out where did I make a mistake, please?
Best regards,
Ijon
