连老师,您好!
运行stata11手册[TS]dfactor postestimation里Example 1的代码,出现错误,调试很久都没有结果,还请您给予指点。
下面是代码(与手册上的一模一样):
use http://www.stata-press.com/data/r11/dfex
dfactor (D.(ipman income hours unemp) = , noconstant ar(1)) (f = , ar(1/2))
tsappend, add(6)
predict Dipman_f, dynamic(tm(2008m12)) equation(D.ipman)
报错信息是:
(option y assumed; fitted values)
option xb with dynamic() may not be used when time-series operators are used on
the dependent variables
r(321);
非常感谢。您辛苦了!
