Hello Friends,
I have 1 material with history of 36 months and I want to forecast for next 18 months. when I use the Simple linear regression model, I am not able to get forecast at all.
Outlier correction is not used. when I use the outlier correction in interactive planning and try to run the forecast, I get the forecast. But as they are using this Simple Linear regression method for bunch of materials and all the other materials are getting correct forecast, I need a proper explanation to give why this technique is not working for this particular material.
As I am new to APO, can anyone explain how this Simple linear regression method works? Also when tried in library and net, I didnot find any document on how the forecast is calculated for linear regression.
Thanks in advance for your help.
Regards
Sameer
