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
Arne

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
