我有一个时间序列的数据:例如:1 2 3 4 5 6 7
请问怎么用“estimate moment conditions by using generalized method of moments (GMM), and use Newey and West (1987) weights on the variance/covariance matrix”??
万分感谢!!!
Proc Model can handle it.
The example of syntax is,
proc model data = sashelp.citiqtr;
gdp = b0 + b1 * bpb;
fit gdp /gmm kernel=(bart,3,0);
parms b0, b1;
run;
quit;
