I need help for ARIMA Procedure results

[iskenderc]

My input and output results of ARIMA procedure are as follows:

INPUT :

proc arima data=poparima  plots  ;

identify var=polag1 ;

run;

identify var=polag2;

run;

identify var=po  nlag=24  stationarity=(adf=3 )  crosscorr=(polag1 polag2  Po3 )  ;

run;

OUTPUT:

Conditional Least Squares Estimation
Parameter	Estimate	Standard Error	t Value
MU	0.19818	0.03490	5.68
MA1,1	1.13442	0.02177	52.10
MA2,1	-0.56556	0.12745	-4.44
NUM1	1.99898	0.01805	110.76
NUM2	-1.00248	0.01810	-55.37
NUM3	-0.20601	0.0032769	-62.87

Moving Average Factors
Factor 1:	1 - 1.13442 B**(3)
Factor 2:	1 + 0.56556 B**(3)

Question is: How should I write mathematical form of the estimated model?

Thanks for your helps
