One approach for the identification of spatially variable genes is the Moran’s I score, a measure of spatial autocorrelation (correlation of signal, such as gene expression, in observations close in space).With Squidpy we can investigate spatial variability of gene expression. This is an example of a function that only supports 2D data. squidpy.gr.spatial_autocorr() conveniently wraps two spatial autocorrelation statistics: Moran’s I and Geary’s C. They provide a score on the degree of spatial variability of gene expression.Squidpy implements three variations of the Ripley statistic Fig. 1 (L, F and G; Supplementary Fig. 2b provides an additional example) that allows one to gain a global understanding of spatial pattern-Indices Commodities Currencies Stocks
