Hi Daniele:

Here is a specific issue I found in QGIS with version 3.2 and above. Dataset: https://goo.gl/AYfXmG When I use this point dataset to do G_Local test and use Fixed Distance Band, it will crash QGIS. Not sure if this issue come from pysal module itself. I tested in both Windows and Linux version, issue applies. Pysal version: 1.14.3 on Linux, 1.14.4 on Windows.

Cheers, Ariel

Dear Ariel,

It looks like the problem comes from outside, i.e. form the proj.4 library (see here). Thus, we cannot solve it by yourself.

Suggestion, why don't use another projection, e.g. WGS84-UTM32N (EPSG:32632)?

By using it, everything works fine on your data and you should not have problems in terms of displacement. This because I guess positional accuracy is not that stringent when dealing with polls data.

Cheers
