I had a little trouble understanding the question. Any implementation of linear regression is going to make these assumptions. They are not going to check them. Normally it is up to you to decide if the assumptions are met and you want to use linear regression. Probably more normally you just try linear regression and see what results you get and don’t worry about the assumptions. 

Pre-checking if the assumptions are met is sort of an interesting idea. I think Eibe was trying to show how you could do this with Weka. 

There are many other classifiers that can be used so it usually easier just to try a few and see which perform best. Weka’s experimenter can be used for this. Or just repeated trial and error. You can also ensemble or use multiple classifiers together to improve performance.

If linear regression is a requirement and you want to be diligent in checking the assumptions. Eibe’s s suggestions would be the way to go.
