Re: R2MLwiN and multilevel multiple imputation
I changed the paths for the R2MLwiN file and the package library so that it doesn't have to go through "My Name" folder that includes a space. But as you can see in the Fatal error below, it still tries to open file "C:\Users\My"... > install.packages("C:/Program Files/R/R2M...

Re: V gone -ve definite for block 0 iteration aborted
That did not fix the problem. I also tried the same model in other mulitply imputed dataset to see if it only works in some datasets, but it did not work in any.

Re: MCMC adding iterations and specifying diagonal matrix
That is a good alternative, thanks!

Re: V gone -ve definite for block 0 iteration aborted
I don't have missing values for gdp_c, and also gdp_c is constant within my level 2 units. It is a level 2 variable so each level 2 unit has a single value for all level 1 units within. This is analogous to modeling complex level 1 variation (i.e., modeling level 1 variance as a function of level 1 ...

Re: variance function and its uncertainty
Any advice on IGLS? To get confidence intervals on the variance functions, perhaps using standard error, or other methods.

MCMC adding iterations and specifying diagonal matrix
Hi, 1) I know in MLwiN, I can run additional interations after running some. For example, I run 500 burnins and 5000 iterations. But, if I find that for some parameters, I need to run more, I can just add more iterations. Can I do this in R using R2MLwiN? I see that in R examples for MCMC manual, in...

Re: V gone -ve definite for block 0 iteration aborted
By the way, I thought the idea of using "starval" to set starting values was similar to clicking "More" after manipulate the model so I tried it but it doesn't help.

V gone -ve definite for block 0 iteration aborted
I have a two-level random slope model shown below. If I run it in R with runMLwiN, I get an error saying "V gone -ve definite for block 0 iteration aborted(fixed pass)" after about 10 minutes. If I use "debugmode=T" in the estoptions, I get MLwiN window without anything on it, an...

Re: R2MLwiN and multilevel multiple imputation
EDIT: for the multiply imputed datasets, I confirmed that there is nothing wrong with each dataset. I ran the model in each dataset and it works fine. I think running it through a loop is causing an issue..? This is related to my new post, it's the same error, one that opens MLwiN and shows nothing ...

variance function and its uncertainty
Hello, I am running a complex level 2 variation model (variance at level 2 as a function of predictors). I know how to get the level 2 variance from this model and graph it. Is there a way to get confidence (or credible, if using MCMC) intervals around the variance function? I can't find any manual ...
