Hi, I am trying to do multiple imputation on a panel of data and then, use the imputed values in stochastic frontier analysis. I am using this code just as a start to see if will run: mi(countrydata, n.iter = 30, R.hat = 1.1, max.minutes = 20, rand.imp.method = "bootstrap", run.past.convergence = FALSE, seed = NA) Unfortunately, I get this error which seems to have to do with the panel nature of the data: Error in function (classes, fdef, mtable) : unable to find an inhe...

...I've merged the attached two data sets, generating a final merged data set, but when I review this merged data, the dates are not in the correct order. I know that this can be solved by using something like fmt<-"%m/%d/%y", but where should this go in the commands below? > Countrydata<-read.table("Desktop/R/Countrydata.txt", head=T, sep="\t") > Dates<-read.table("Desktop/R/CDSdate.txt", head=T, sep="\t") > Merged<-merge(Dates, Countrydata, all.x=T) > edit(Merged) Also, I thought all.x=T was supposed to fill in every m...

...e in value. What I have done is merged the attached data files, and filled in the missing values this way: > fmt<-"%m/%d/%y" > dd<-read.csv("Desktop/R/CDSdate.txt") > dd$Date<-as.Date(dd$Date, fmt) >library(zoo) > data<-read.zoo("Desktop/R/Countrydata.txt", head=T, format=fmt, sep="\t") >newdata<-merge(data, zoo(,dd$Date) >Finaldata<-na.locf(newdata, fromLast=TRUE) Now, I have to break up this Finaldata. I've been told to do something like this: # first make up some data jym.df<-data.frame(country=rep(c(&qu...
