BTW, Junqing, listers would certainly like to hear from you how the lagged
values are "wrong". It could mean different things to different people, so
you should give an example of what it is that bothers you about them. In my
example, everything seems normal:
***
clear*
set obs 100
//id
gen id=_n
//expand to # of time periods
expand 10
bys id: gen time=_n
gen x=rnormal()
compress
mi set wide
mi tsset id time
by id: gen lagx=l.x
l in 1/50, sepby(id)
***

Subject: st: stata generated wrong lagged values for mi data
My data is panel data in mi format. I used the following syntax to
generate several lagged varaibles(one time point lag) one by one:
mi tsset ID time
sort ID time
by ID, gen lagx=l.x
But i found that the generaged lagged values of panels were wrong. How i
may fix it? Thanks a lot.
