I'm doing a linear regression with a data set that have about 500k rows and 66 attributes, I'm running rapidminer on a windows os, rapidminer is using 8 gb of mem only for itself and a processor xeon 2.4GHz. These are my problems:
First: The process takes about 40 minutes to finish, it seems a lot of time compared with other tools I've used
Second and more important: in the values of the p-values and std error and some other metrics I get an "?" (question mark), I don't know what that means and I starting to think that is something wrong with rm. I'm including a picture with the results
Thank you very much!!!
