[R-sig-Geo] Spatiotemporal autocorrelation in R

[Laura Cabral]

Hello All,

I have been reading about spatiotemporal autocorrelation and slowly familiarizing myself with the concepts involved. I have also been combing through the CRAN spatiotemporal task view, but I can’t seem to find the appropriate package/function for my purposes.

What I want to do: 
I have two series of count data each for the same times and locations. Both series have been ordered from lowest count to highest count. I would like to identify where/when in space-time the series are similar (low-low count clusters, high-high count clusters) and where they do not correspond (high-low or low-high). Really, I am looking for a Moran’s I type index which can handle spatiotemporal data. I know this type of index has been developed (see for example Shen, Li and Si, 2016 - Spatiotemporal autocorrelation measures for nonstationary series), but I am unsure whether any of it has been translated into an R package/function. I do not (yet) have the mathematical/statistical/programming knowledge to implement those myself.


What I don’t want to do:
I have seen quite a bit of discussions or packages aimed at detrending or modelling the data. I do not need these functionalities. I have also seen separate handling of spatial and temporal autocorrelation for the same dataset. I would prefer an integrated index, if that is possible.

I feel like I might be looking for the wrong keywords, so any keywords, packages, functions, tutorials, videos, etc. that you could recommend would be greatly beneficial. As I mentioned, I am still familiarizing myself with spatiotemporal autocorrelation concepts, so if I seem to be approaching this from the completely wrong angle, please let me know!

Thank you all for your help,

Laura Cabral
