GWRResults.local_collinearity(self)[source]

Computes several indicators of multicollinearity within a geographically weighted design matrix, including:

local correlation coefficients (n, ((p**2) + p) / 2) local variance inflation factors (VIF) (n, p-1) local condition number (n, 1) local variance-decomposition proportions (n, p)

Returns four arrays with the order and dimensions listed above where n is the number of locations used as calibrations points and p is the number of explanatory variables. Local correlation coefficient and local VIF are not calculated for constant term.
