    spatial regression with (partly) overlapping areas

    Dear forum, Is it statistically correct to calculate a regression with overlapping areas? I have market areas as the spatial unit with different sociodemographic and (macro)economic variables and I´m examining their influence on insurance demand. The market areas are overlapping in some areas...

    Sound propagation modeling (with lme, unequal sample size, and "drop out" problems?)

    I conducted a sound propagation experiment in which 20 different recorded roar-barks (the long distance vocalization of maned wolves) were played back at different sites(x3), hours(x6: 17h,18h,23h,05h,06h,11h), and with different speaker position (x2: straight forward and inclined upward 45o)...

    Moran's I Spatial Autocorrelation. Interpreting results.

    I have carried out a Moran's I test on the residuals of a GLM model in the "ape" package in R which has returned the output below: Observed: -0.158 Expected: -0.0303 SD: 0.058844 Probability: 0.030002 On this basis is it correct to state that there is negative spatial autocorrelation...

    Accounting for spatial autocorrelation in neural network analysis in R

    Hi all, I have been exploring the use of neural networks to identify relationships between large numbers of differing species and the presence of a specific bacteria in the environment. Previously I had been using mixed effects models, as I could account for spatial autocorrelation in my...
