Hi,
I have a time series with the following independent variables:
time, vendor, product, miles driven
time is the time variable
vendor and product are categorical variables
miles driven is a quantitative variable
Will it be statistically correct if I did the following:
proc autoreg data=MyData;
class vendor product;
model sales = vendor product miles_driven;
run;
Its just that the few times when I did time series I only had time as an independent variable, but here there are categorical and quantitative variables as well so I just want to make sure that using the proc autoreg will yield meaningful results.
Thank you
