When I run kriging a+bx or any other model, I always get just one constant output. I have selected collect attribute. Prediction and quality layer has just one value.

see output here:

maximum distance -1. What is that doing? – If you do not know- just GIS Mar 01 '19 at 21:51
Just checking you have built statistics on the output or ran info to check that is all the values in the raster – If you do not know- just GIS Mar 01 '19 at 21:52
-1 is default value. i tried 10 and 100 as well. – QGIS_krig Mar 01 '19 at 22:15
I think its lacking documentation as the moment. – If you do not know- just GIS Mar 01 '19 at 22:17
Min and Max in 'quality measure' and 'prediction' layer are same. – QGIS_krig Mar 01 '19 at 22:20
Hi QGIS_krig and welcome to GIS SE. How have you set Variogram model in the dialog? You might be in a similar situation as I was before; Variogram model - SAGA on QGIS Processing – Kazuhito Mar 01 '19 at 22:28
i tried default a+bx and then i tried a+bx+cx^2+dx^3. i see that it calculates some value for a,b,c,d parameters. – QGIS_krig Mar 01 '19 at 22:37
