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.
