[R] Library(mice) too slow for my dataset

Dear Teresa,
using such services will only speed up the imputations significantly if you can split up/parallelize your code.

And maybe you can use more cores on your local machine by using packages like doSNOW, foreach and/or plyr. There are a lot of examples on the web.

Kind regards

Betreff: [R] Library(mice) too slow for my dataset

Hi to everyone

I have a big dataset (40.000 columns (variables) and 50 rows)

I want to impute a lot of  variables  with  library(mice), the problem is that this process is too slow (because of my dataset, the library is brilliant).

I am looking some options like Amazon web services, ( http://aws.amazon.com/es/datapipeline/developer-resources/ )

Has anyone used this service or knows other options?

Any ideas are welcome.

Thanks in advance
