Questions tagged [gwr]

Suitable if you have a question about Geographically Weighted Regression module of your environment.

Geographically weighted regression is a spatial analysis technique that takes non-stationary variables into consideration (e.g., climate; demographic factors; physical environment characteristics) and models the local relationships between these predictors and an outcome of interest. Suitable if you have a question about GWR module of your environment.

Would you explain GWR model results are make another variables?

I'm using GWR model in Python how many spatial characteristics affect in my results. I try to use 14 variables, but GWR results are not presents variable name but also x0, x1, ... and the results show me x0, x1, ... x14, input variables are 14, but…

Problem with finding Bandwidth for MGWR in python

So im using python and trying to do a MGWR When looking for bw for my GWR I used >>> gwr_selector = Sel_BW(g_coords, g_y, g_X) >>> bw = gwr_selector.search(bw_min=2) >>> bw and it worked fine. I am trying to do >>> mgwr_selector = Sel_BW(g_coords,…

Why do my arrays display missing values when identifying a bandwidth? (geopandas)

I'm trying to identify a suitable bandwidth to use for a geographically weighted regression but every time I search for the bandwidth it displays that there are missing (NaN) values within the arrays of the dataset. Although, each row features all…

Apply geographically weighted regression's model parameters to a finer spatial scale

I have two raster layers, one coarse resolution and one fine resolution. My goal is to extract GWR's coefficients (intercept and slope) and apply them to my fine resolution raster. I can do this easily when I perform simple linear regression. For…

How to obtain standard errors of local regression coefficients in spgwr::ggwr()?

I am using spgwr::ggwr() to fit generalized geographically weighted regression with Poisson model and log-link function. The results provide local coefficient estimates, but i am missing how to get their standard errors (or t statistics) to compute…
