Dear Jan , Could you please help me with the error of nwxtregress

Dear Jan,
I run the demo code in your github , eg VA data set to estimate a SAR mode, the estimation process goes smoothly but while I try to get the imact, estat impact, it returns the following errors:
estat impact
----+--- 10 --+--- 20 --+--- 30 --+--- 40 --+--- 50 %
*: 3200 conformability error
SparseMultiply(): - function returned error
BarryPace(): - function returned error
calc_DIEffects(): - function returned error
: - function returned error

As you methioned in one of the discussion, I need to install the new version of moremata library in Stata. The problem is that even I install it, the errors are still there, I sincerely hope that you can help me.

the coding is just like this :

use IO
keep if Year == 1998
drop buyer_industry seller_industry
replace sam = 0 if sam < 0
replace sam = 0 if ID1==ID2
reshape wide sam, i(ID1) j(ID2)
spset ID1
spmatrix fromdata WSpmat = sam* , replace
clear
use VA
nwxtregress cap_cons compensation net_surplus , dvarlag(WSpmat) seed(1234)
estat impact

Thank you very much!

Thanks for the pointer - this was indeed a bug in the code. The error occurred if a non sparse weight matrix was used.

I pushed an update to GitHub, please check and let me know if the error remains.

Thanks a lot, Jan! It works. Terrific coding for spatial network estimation!

Perfect, thanks a lot for letting me know. Please get in touch if you have any other questions or comments.
