看命令的帮助问题
第一个是没有问题的
第二个,pvar2命令的帮助里面没有gmm选项
[XT] pvar2 -- Panel Vector Autoregressive Models
Syntax
pvar2 depvarlist [if] [, lag(#) irf(#) irfformat(%fmt) reps(#) decomp(#) nograph residual
saving(filename) timeeffect soc granger seed(#) ]
options Description
-------------------------------------------------------------------------------------------------------------
Model
lag(#) specifies the number of lags in the underlying VAR; default is 1; # has to be integer >0.
Note that, when option granger is specified, # must be no less than 2.
irf(#) calculate the impulse response function and generates error bands for impulse-responses
using monte-carlo simulations. # specifies the steps in calculating the
impulse-responses.
irfformat(%fmt) display format for y-axis labels in the IRF graphs; default format is %6.3f.
reps(#) The default number of repetitions of Monte Carlo simuliation is 200. If you want change
the repwtitions, just specify the number in reps(#).
nograph By default when irf(#) is specified, the IRFs graphs will be drawn. Specify nograph will
not display the IRFs graphs, but the IRFs dataset will still by saved.
