about Linear Regression - Palu11 - 02-28-2016 03:47 AM

hi,
I am new to this forum.
Just found out about DataMelt.

I am trying to figure out how to try out DataMelt in java for Linear Regression, specifically for Multi-Linear Regression.

I see that there is a community edition, but also a paid single user, multiuser and commercial license.

Can someone let me if one can try out DataMelt for free, community edition, to get documentation or code for Linear Regression.

Also, which algorithms does DataMelt use for Linear Regression:

1) OLS - Ordinary Least Squares
2) SGD - Steepest Gradient Descent

I am needing the OLS way.

Hope someone can help me with these questions.

P
