Hi

it's difficult to diagnose the issue here, but the large number of post-EM iterations is suspicious. Did you try estimation via apollo_estimate instead of EM first? That might better highlight any identification issues

I suggest that for this model, you use apollo_estimate as the EM implementation is at present likely not suitable for it

Hi

I can try to debug this for you if you share the model and data file with me outside the forum

Thanks

Hi sorry, your message had got lost Apollo tells you that you should have the following order of operations: 'apollo_panelProd' after calling 'apollo_lc'. In your model, you need to move apollo_panelProd and apollo_avgInterDraws to be outside the loop, after P[["model"]] = apollo_lc(lc_set...

Anat modelled outcomes is the number of separate dependent variable observations. Relative function convergence is the BGW terminology for convergence. Using rows=(task==1) is correct, and will indeed give you different estimates as you don't overstate the weight for the measurement model part Steph...

Hi

it looks like you are not including those socio-demographics in the random coefficients, so they would not affect the MRS

Regarding your code, you will want to use subset instead of multiplication by a 0/1 indicator

Hi

please update to the newest version of Apollo and see if that fixes it

Thanks

Hi

can you tell us more about your data, i.e. how many levels there are for each of the attributes

Hi Cuong You have 3 alternatives, but you are only estimating one constant. You can estimate J-1 constants, i.e. 2 My question was whether your third alternative in the survey is different from the other two, i.e. does it use different levels, etc? Regarding categorical, what I mean is that you dumm...

Can you provide us with a bit more detail, please, e.g. a screenshot of a SC task?

Thanks
