Auto-correlation applies in the field of statistics and probability. It measures the correlation of a variable with itself when there is an observation of an offset in space. The spatial autocorrelation is observed when the presence of a quality in a part of a territory makes its presence in the neighboring areas more or less probable and there is an adjacency in the spatial structure. The autocorrelation is considered positive when neighboring regions tend to have identical properties or similar values. It is negative when neighboring regions have different qualities, or when strong and weak values ​​alternate.
