Dear Statalist,
I am using Stata 15. and I am working on spatial (SAR) model with panel data. I have difficulties:
1. I can not linked the shape file --> I have the coordinates (lat and long) so I chose estimation without shapefile.
2. When I type : spmatrix create idistance W, it says: Two or more observations have the same coordinates. Of course the banks will have exactly same coordinates each time observations. What should I do?
3. When I remove the bank with some coordinates (that is meaan the data become cross section) it says:
Any advise is much appreciated. Thank you

| spxtregress ROA SIZE CAPITAL, fe dvarlag(W) |
| (45 observations) |
| (45 observations used) |
| (data contain 45 panels (places) ) |
| data contain fewer than 2 time periods |
| r(459); |
Any advise is much appreciated. Thank you
I'm currently working on a spatial (SAR) model and am running into the same problem's as you've mentioned. Did you find a solution?
