Proc Varmax - Missing output

Hi,

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;

run;

But when I get the output I don't get all the parameter estimates, there are some missing:

Model Parameter Estimates
EquationParameterEstimateStandard
Error
t ValuePr > |t|Variable
salesMA1_1_10.723490.0319622.640.0001e1(t-1)
MA1_1_21054.211530.00000e2(t-1)
tempMA1_2_1-0.000000.00000e1(t-1)
MA1_2_21.005580.00000e2(t-1)

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!
