Greetings !
My Entry Level Quest(ion) is finding an iterative process for autoregressive forecasts.
Objectice: Create 155 customer forecasts and see estimates and p values of invovled variables
What I've done: I have created an autoregressive forecast for a customer, normalized its history and pulled out the pvalue and estimates for the variables.
Help I need doing: I want to do this for 155 customers (i.e CustomerID= 138,158, 37....) and create a table for the variable estimates and table for pvalues.
Attached: Is the SAS code (SASDOLOOP) and Excel Input File(Autoregression). In the Excel file I have in the last two tabs EstimateOutPut and Pvalue Output the desired format of the output results.
Without reading your code or getting into the data, generally if you want to repeat a process for a specified set of groups you can use BY Group processing. Basically, stack your data together so you have a variable that identifies each customer, with everything else the same as it was before and then add a by line into your proc.
proc whateever;
BY Customer;
rest of the code is the same;
run;
Thank you for your reply. If you are able to see my code, how is that I can stack them according to Customer? Also can anyone tell me how to build a table specified above.
Is your HDD_30_158 where 158 is your customer ID?
If so you'll need to transform the data so that is instead, but you have a lot of data and a bit of code and I don't have enough time to look into it further
CUSTOMER HDD_30
158
252
