I am using proc varmax to analyse the relationship between sales (some very high values) and temperature (between -0.9 and about 15). I have differenced both seasonally and taken the first differences and trying to use an MA1 model on it using the code:
ods graphics on;
proc varmax data = merged1 outest=est outcov outstat=stat;
model sales temp/q=1 dif(sales(1 12) temp(1 12)) print=(corry) noint;
But when I get the output I don't get all the parameter estimates, there are some missing:
|Model Parameter Estimates|
|t Value||Pr > |t|||Variable|
Does anyone know why I only get the t and p value for MA1_1_1?
Any help would be greatly appreciated!
Thanks a lot!
