Tool Statistics for Grids

Calculates statistical properties (arithmetic mean, minimum, maximum, variance, standard deviation) for each cell position for the values of the selected grids.
Optionally you can supply a list of grids with weights. If you want to use weights, the number of value and weight grids have to be the same Value and weight grids are associated by their order in the lists. Weight grids have not to share the grid system of the value grids. In case that no weight can be obtained from a weight grid for value, that value will be ignored.
