Generalized linear modelling in periglacial studies: terrain parameters and patterned ground
Abstract Generalized linear models (GLM) are mathematical extensions of linear models. GLM models are more flexible and better suited for analysing relationships of spatial data, which can often be poorly represented by classical Gaussian distributions such as least‐square‐regression techniques.
