1.Sobel检验中,标准误、Z值和P值都没有(如下图),请问是什么原因? 2.在另一个模型中,我想用的自变量是滞后一期值L.X,但是当我输入sgmediation Y, mv(Z) iv( L.X)时候,输出结果提示:factor-variable and time-series operators not allowed(error in option iv( )),这种情况怎么办呢? 1.几个小时前一...
Dear Statausers, When I run this command: tsset dtt probit y l.x1 l.x2 mfx I get the following error: factor variables and time-series operators not allowed r(101); What could be the reason for no mfx for lagged variables in time-series? Or am I missing something? Any comments woul...
Why is my command not working with factor-variable syntax and/or collinear variables in Stata 11? Answer: As of Stata 11, variables are no longer dropped because of collinearity. Instead, these variables are omitted and are labeled with an “o.” operator in the column names of the resultin...

Capex and variable opex are assumed to escalate at the GRI of 5% p.a., and no market factor is applied. Fixed opex is a fixed percentage of the cumulative MOD capex. Care is taken not to simply escalate the sum of fixed plus variable BYC opex as this would double-count on the fixed...
Non-planar Feynman diagrams can contribute to leading-color form factors of color-singlet operators — provided that the diagram becomes planar when one deletes the external leg corresponding to the operator.) The two-loop symbol only requires 34 out of the 113 letters. The three-loop symbol ...
