GDM without Coordinates

Hello, I would like to perform GDM, but my data comes from a designed experiment so the geographical distance do not provide much information. Therefore, I would like to know if it is possible to apply GDM without adding this information.

Thanks in advance

I believe that spatial distance is not necessary -- you just need one or more variables to calculate distances relating to the differences in these variables between locations. If you measured some variable at these locations, you can use them to calculate a distance matrix. Jamie

Thanks for the reply. In that case I can add it and then set geo = F, right?

Thanks again,
Marcio

Yes, I believe so, but the authors of the package can confirm.

@Leitemfa @jamiemkass is correct. You can simply set geo=F as long as you have at least one other environmental variable for model fitting.
