RE:  Amelia for R produces no imputed output files [WAT Issue #1]

 

 

PROBLEM:  After running Amelia to generate 5 imputed files, no imputed data output files were generated.

 

BACKGROUND:  Here is my command line to run Amelia:

 

*******************

CONTROL PANEL

*******************

 

impruns  <- 5   

tolX     <- 0.0001 

empriX    <- 100 

autopriX  <- 0.05

resampleX <- 100 

 

***************************

CONTROL PANEL

*******************

 

      imputed <- amelia(DATA8i,

                  m  = impruns      ,  p2s = 2      ,                         idvars = c(3,4,5)   ,

                  ts = 1         ,  cs  = 2     ,    polytime  = NULL,

                                                      startvals = 0   , tolerance = tolX    ,

                                                                        noms = nomIV8i      ,           

                  ords = ordIV8i ,  incheck = T  ,       collect = F     , outname = "DATA8imp",

                  write.out = T  ,     archive = T ,                         keep.data = T    ,

                  empri = empriX ,                                      autopri = autopriX  ,

                  bounds = IVlims,                    max.resample = resampleX               )

 

 

After a run in which Amelia did not generate the expected output files (…DATA8imp1, DATA8imp2, etc…),

I am able to extract output info from…

 

      imputed[[ ]]

      imputed.rData
