با سلام
میشه لطفا توضیح بدید که در این فرمول مورد اشاره، رگرسورها شامل متغیر وابسته با وقفه در مدل میشه یا تنها متغیر های توضیحی در نظر گرفته میشه؟Dependent Variable: RTRADE Method: Panel Generalized Method of Moments Transformation: First Differences Date: 01/26/14 Time: 18:28 Sample (adjusted): 1995 2012 Periods included: 18 Cross-sections included: 31 Total panel (balanced) observations: 558 White period instrument weighting matrix White period standard errors & covariance (d.f. corrected)Instrument specification: @DYN(RTRADE,-2,-3) @DYN(LINDER1,-2) @DYN(REXCHANGEP,-2) LINDER1 GDPP GDPIRIConstant added to instrument list VariableCoefficientStd.
