importing explicitly declared missing values in read.spss (foreign)
...roblem when importing an spss-file containing explicitly declared
missing values in R using the read.spss function from the foreign package.
I'm not sure these problems are the same in every version of spss, I am
using the latest version 16.0.2.
I included http://www.nabble.com/file/p18776776/missingdata.sav
missingdata.sav and http://www.nabble.com/file/p18776776/frequencies.jpg
frequencies.jpg as an example. The data contains 3 types of missing data: 2
are explicitly declared as a missing-value ('8' = NA and '9' = NAP), the
third type are the system missings. When this file is...

Need help to create a monotone missing data pattern
Hi
I've simulated multivariate longitudinal. The data is a mixture of conitnous
and categorical data. I've stored it in matrix form with the time dependent
variables as colons. Now I want to create a monote missing data pattern
starting of with MCAR-missingnes and different proportions of
missingdata and then refine the function to handle MAR and NMAR. Is there
anybody that could help or point in the right direction.
