Re: Setting up an AR(1) model

Got it, Chris. Is it possible to setup a similar model as the Rats example in Chapter 19 with two outcomes like I have here?

Setting up an AR(1) model

Hi Chris, George, and all, I hope everyone is doing well. I have a question about setting up and running a growth curve model that has the additional wrinkle of allowing for an AR(1) structure to the residuals. I have looked at the MCMC manual, chapter 19, and seen the example with the rats dataset....

Re: Number of groups varies between 2- and 3-level multivariate MLM

Thanks, Chris. Knowing the CC exists and it is so easily handled in MLwiN, I agree it makes sense to model it correctly. I did so and variance and covariance estimates at each of the levels are quite similar, and as a result, the number of groups being reported is exactly aligned with expectations.

Re: Number of groups varies between 2- and 3-level multivariate MLM

Thanks, Chris. You identified the problem exactly. I have two teachers who each taught in two different schools. Technically that means teachers and schools are cross-classified. However, with only two of 65 teachers in this situation, I'm curious whether you think it makes sense to model the cross-...

Number of groups varies between 2- and 3-level multivariate MLM

Hi all, I am running a multivariate MLM that has repeated observations (level 1) of teachers (level 2) within schools (level 3). The data has 550 non-missing observations on the two outcomes for 65 teachers in 23 schools. Variable | Obs Mean Std. Dev. Min Max -----------------+----------------------...

Re: MLwiN Manual Chapter 18 Cross-classified code

Ah, I see. Yes, I did not clear the constraints when I re-ran the model after re-loading the data.

Thanks, Chris!

MLwiN Manual Chapter 18 Cross-classified code

Hello, I am trying out the code provided for runmlwin to replicate the analyses in the MLwiN Users Manual (thank you for doing that, Chris and George!) and I have a question about some of the code for cross-classified models in Chapter 18. To run the model in 18.4, the runmlwin .do file has the foll...
