Re: Characteristic is not defined at correct level of analysis

Dear Chris,

Thank your for your quick reply.

However, I actually do use MCMC (with the cross-classification option turned on).
When I add my country-cohort characteristics, the variable has a lm-subscript (which corresponds to the cohort level).
Do you know whether something else could cause this ...

Characteristic is not defined at correct level of analysis

Dear all,

I am trying to run a model that has a nesting structure as shown in the attached figure.
However, when I want to incorporate a country-cohort characteristic, MLwiN does not recognize it as defined at this level (neither in IGLS, nor in MCMC). MLwiN considers it as a cohort characteristic ...

2nd order PQL - no convergence

Dear all,

I want to conduct a two-level nested model using longitudinal data (level1 = observation, level2=ID).
My dependent variable is a binary outcome.

When I try to fit my nullmodel using 2nd order PQL (based on the starting values of 1st order MQL), my model does not converge.
I am not sure ...

Re: Multinomial: MCMC

Dear Chris,

The zoom-function worked well.
As you can see, the covariance matrix is not similar to the covariances of the IGLS model
(especially the numbers I changed in column 1096).

Thanks,
Katrijn

Re: Multinomial: MCMC

Dear Chris,

I cannot scroll down to the bottom to see the priors for the covariance matrix (as I have 65 coefficients).
Is there another way to see them?

Many thanks,
Katrijn

Re: Multinomial: MCMC

Dear Chris,

Thank you for your quick reply!

I'm using version 2.35, so that cannot be the problem...

I do not exactly understand what you mean, but I added a print screen of my priors (I couldn't see all the priors, but I guess they are all equal to 1).

And no, my dataset only contains 20 ...

Multinomial: MCMC

Hi

I want to carry out a multinomial multilevel analysis in MlWin, using the Markov Chain Monte Carlo estimation procedure, but I'm having some difficulties.

When I switch from 1st order MQL to 2nd order PQL, I lose all my cases (while my data contains no missing values).
So, I tried to go ...

Re: MlWin gives different results to Stata/R

Dear Chris,

I’m using version 2.31 of MlWin and the data contained no missing values.
The MCMC convergence criteria were met (ESS > 400 and the trajectories look fine).
I added a screenshot and further information as attachment.

Many thanks,
Katrijn
