Hi Laura, Yes, if you can email me a small do-file and dataset which replicates the bug you describe that would help us fix it. If the model is unstable or missspecified you may have an extreme or non-sensical log-likelihood value which gets reset to Stata's system missing value when we import the M...

Dear Corrie,

The norecode option should now be implemented

You can get the latest version of runmlwin by typing the following into Stata
Best wishes

George

Note that a newver version of runmlwin have since been released

To get the latest version simply type

Dear Belkacem, The latest version of runmlwin is now available and should work in Stata versions 9, 10, 11 and 12 Upgrade to the latest version of runmlwin by issuing the following command . ssc install runmlwin, replace Please do let us know whether runmlwin works for your colleague on his version ...

Dear Julia, Three general pieces of advice regarding MCMC and initial values: (1) Always try to specify reasonable initial values. Using mq1 estimates for exactly the same model specification is a good way to do this. (2) The longer the burnin the less sensitive your MCMC parameter estimates will be...

Hi Kate, Thanks for your interesting query. Yes you can use the runmlwin command to fit multilevel mixed response models in MLwiN. Consider the MLwiN tutorial data set. We can fit a two-level (students nested within schools) mixed response model for normexam (continuous) and binlrt (binary) as follo...

Hi Queena, The only way to fit AR1 residual errors to repeated measures data (measurement occasions at level 1, nested within individuals at level 2) is to formulate the model as a multivariate response model and to fit this model using MCMC. You cannot fit the equivilent model using IGLS (i.e. maxi...

Great question! Yes you do need to sort the data according to the model hierarchy before running the runmlwin command for the model. However, the nice thing about runmlwin is that runmlwin will automatically tell you if the data is sorted incorretly, so you do not need to worry that you have sent mi...

Hi Laura, I suspect that one or both of you might not be using the latest version of runmlwin. You can check which version you are using by typing . which runmlwin and you will get output which looks something like the following . which runmlwin C:\ado\plus\r\runmlwin.ado *! runmlwin.ado, George Lec...

Hi Raphael, First note that for continuous response models the log-likelihood is provide and so for these models you can calculate LR tests, AIC and BIC statistics by making use of Stata's lrtest and estat ic commands. It is for discrete response models (i.e. models for binary, count and categorical...
