Dear Sir and all group members,

I hope you are doing well.

I am interested in learning the Grey Influence Analysis (GINA) technique for my research work. I would be grateful if you could suggest any reliable platform, course, workshop, or training resource where I can learn this technique.
Your guidance and recommendations would be greatly appreciated.

Thank you for your time and support.

Kind regards,
Ruby Sharma

Sending you the worksheet with GINA Analysis

It is one DV Sales and four IVs  Ad Spend, Price, Staff and Competitor Price

Column B to F : Original Data

Column H to L : Calculation of Min-Max normalization used  to make all values  0-1.

Column M to Q : Absolute difference between DV and each IV at each point.

Column R to U : Grey Relational Coefficients

For DV and all the IV it is assumed that bigger value is better

Results are as under
