[R] mitools and plm packages
Hi all, I am trying to use the functions in the plm package with multiply imputed datasets. I had tried to combine the datasets using the imputationList() function of mitools. plm, however, requires a data argument, and I don't know where to point it to. I'd appreciate any help people might have. A (possible) fuller description of the problem and code is in a previous message: https://stat.ethz.ch/pipermail/r-help/2007-August/ 138670.html. Thanks. -N -- Nathan A.

[R] Panel data and imputed datasets
Hi all, I am hardly an expert, so I expect that this code is not the easiest/ most efficient way of getting where I want. Any suggestions in that direction would also be helpful. I am working on panel analysis with five imputed datasets, generated by Amelia. To do panel analysis, it seemed that the plm package was the best, providing a convenient wrapper for fixed and random effects and Hausman tests. And since I've got five datasets, it seemed reasonable that what I wanted to do was to combine these as a big imputation data frame. The plm regression function requires a data argument, and simply using the imputationList result didn't work, nor did calling the names(allhiv) work (that resulted in imputations and call). Where do I point the plm command to look for the data? Or have I gone about this in entirely the wrong way? Thanks in advance for the help. Best, -N Here's the code I have so far: #Read in the imputed datasets data1 - read.dta(outdata1.dta) data2 - read.dta(outdata2.dta) data3 - read.dta(outdata3.dta) data4 - read.dta(outdata4.dta) data5 - read.dta(outdata5.dta) #Set the datasets as panels (for subsequent analysis in plm) pdata.frame(data1, country, time=year) pdata.frame(data2, country, time=year) pdata.frame(data3, country, time=year) pdata.frame(data4, country, time=year) pdata.frame(data5, country, time=year) #Using mitools, combine the panel data frames 1-5 allhiv - imputationList(list(data1,data2,data3,data4,data5)) #A test regression form2-APIPolSupport~subnatexpoftotal+adultprev.lag+pressfreedom #The following is something I tried but which didn't work. estimateHIV1 -with(allhiv, plm(form2, data=imputations[1:5,])) -- Nathan A.

[R] mice package
Hi all, I am trying to run the mice package (for multiple imputation) on a data frame that is 5174 x 100. When I run mice(frame), I get the following response: Error in solve.default(t(xobs) %*% xobs) : Lapack routine dgesv: system is exactly singular and execution stops. I'm no expert at matrix algebra, so if someone could explain this to me and what I can do to get around it, I'd be very appreciative. Thanks. Best, -N. -- Nathan A.

[R] Mac OS X crash bug?
Hi all, I want to check if this is a bug for which I should file a report. I am using R2.5.0 on OS X 10.4.9. When I invoke the data editor and when I change the values of individual cells, it seems to work as intended. However, when I try to delete/add a row/column, R.app crashes. I've attached the crash log.
