Como o desvio padrão é calculado para o número de rasters na ferramenta Estatística de Célula?
A saída é um raster onde cada pixel representa o STD. Quero entender a equação por trás disso.

How Cell Statistics works—ArcGIS Pro | Documentation
The basic STD equation uses the population method and not the sample.
Note that the standard deviation is calculated on the entire population (the N method); it is not estimated based on a sample (the N-1 method).
There's nothing complex going on, its the STD calculated from coincident raster cell values.
