Hello!

Does anyone happen to know if it's possible to calculate geometric mean as a summary statistic in ArcGIS 10.1?

Thanks,

Amy

Thanks for the suggestion! Do you know if I would be able to use the Mean Center tool to calculate geometric mean (as opposed to arithmetic mean) for a field that contains numeric values (such as integers or floats), rather than the shape's geographic coordinates?

Take care,

Amy

For more information, take a look at the "how it works" doc.

Although the data I'm working with is spatial in nature, the statistical calculation (described here: http://en.wikipedia.org/wiki/Geometric_mean) would not require using a feature's spatial information. For example, if performing a Dissolve, I would like to use the geometric mean (as opposed to arithmetic) as a merge rule.

Not that I know of. I'll have to do some checking. For sure Dissolve doesn't have the option.

Thanks! I'm sure it could be done with some Python scripting, but it would certainly be quicker and easier if a geoprocessing tool such as Dissolve provided that option. I thought it couldn't hurt to ask. :)

Hi Amy - Did you ever find a way to do this in ArcMap?

Hi! We ended up using Python scripting outside of ArcMap and arcpy.
