    Give us the possibility in the summary statistics tool to calculate weighted averages, where the weights are taken from another field. Currently the tool only allows to calculate simple averages (among other statistics like min, max, mean etc.). The corresponding statistics tool in ArcInfo Workstation allows calculation of weighted averages since the beginning, so I am wondering why the summary statistics tool is lacking such option.
