Spatial analysis | Covariance and correlation
Geary's C is a measure of spatial autocorrelation or an attempt to determine if adjacent observations of the same phenomenon are correlated. Spatial autocorrelation is more complex than autocorrelation because the correlation is multi-dimensional and bi-directional. Geary's C is defined as where is the number of spatial units indexed by and ; is the variable of interest; is the mean of ; is a matrix of spatial weights with zeroes on the diagonal (i.e., ); and is the sum of all . The value of Geary's C lies between 0 and some unspecified value greater than 1. Values significantly lower than 1 demonstrate increasing positive spatial autocorrelation, whilst values significantly higher than 1 illustrate increasing negative spatial autocorrelation. Geary's C is inversely related to Moran's I, but it is not identical. Moran's I is a measure of global spatial autocorrelation, while Geary's C is more sensitive to local spatial autocorrelation. Geary's C is also known as Geary's contiguity ratio or simply Geary's ratio. This statistic was developed by Roy C. Geary. (Wikipedia).

RubyConf 2021 - Building Native Extensions. This Could Take A While... by Mike Dalessio
"Native gems" contain pre-compiled libraries for a specific machine architecture, removing the need to compile the C extension or to install other system dependencies. This leads to a much faster and more reliable installation experience for programmers. This talk will provide a deep look
