¿Cómo se calcula la desviación estándar para el número de rásters en la herramienta Estadística de celdas?
La salida es un ráster donde cada píxel representa la STD. Quiero entender la ecuación detrás de esto.

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.
