Howdy, Grus
If this message is overlapped, please forgive me.
I have some troubles with SPLM package of R.
I am trying to estimate some parameters and their model using SPML in SPLM
package of R.
Could you tell me some tips to solve my problem below ?
--------------------------------------------------------------------------------------------------------------------------------------------------------
...
fm.2 <- mr2.tent ~ Census + Den + CmtSch + CmtPop + SchPop + StayPop +
DayPop
+ firm + firm500 + RegWrk + GrsWrk + MnfFirm + MnfReg+ MnfGrs
...
> fespaterr <- spml(fm.2, data = mega.data, listw = mat2listw(megaww),
model="within", spatial.error="b")
Error in model.frame.default(object, data, xlev = xlev) :
variable lengths differ (found for 'Census')
>
For variaable reference,
Y variable is mr2.tent.
X variables are population and firm workers.
Population is Census, Den, CmtSch, CmtPop, SchPop, StayPop, DayPop.
Firms are firm and firm500.
Firm workers are RegWrk, GrsWrk, MnfFirm, MnfReg, MnfGrs.
