Hi,
I have the below dataset and need to normalize each attribute using the below formula for Linear regression model.Then display those attributes as well. I tried different operators but couldn't proceed.
a1 a2 a3 Normalizea1 Normalizea2 Normalizea3
2.3 2.5 3
1.2 1.3 2.4
Formula - normalize a1 = (a1-avg)/std deviation
(here std deviation is max-min)
Ex- (2.3-1.75)/(2.3-1.2)
Any help on this would be greatly appreciated!

Hi,
did you try normalize + Linear Regression? That should work.
