Logistic Regression


#1

Hi,

I am preparing to run logistic regression over 80TB of data (credit scoring), and have two major questions:

  1. Does the ‘logistregr’ function utilize ScalaPACK?
  2. Does the connector for R allow me to run the logistic regression package ‘glm’ from R in a true parallel fashion over a SciDB cluster?

Any feedback is very much appreciated!

Thank you,

Hi Austin

No, the logistregr you must be looking at probably came from the 12.7 demo version. It’s a custom-written prototype and it does not use ScalaPACK yet. The plan is to write a scalapack-based logistregr function, but not in the immediate future. Given what you want to do, you could talk to Paradigm4 Inc about possibly starting a commercial project - email info@paradigm4.com if interested.
