Hi Rich,
When generating reports, is there a way to get error for the entire list of compiled stands? The sample summaries give SE and CV for each stand, but it would be nice to see overall SE for a given inventory project.

Will the Stand Table report for a unit work? Sample Summary is currently only by stand.
Run the Stand Table report for a unit with the stands you want selected (blue). SE at a Unit level treats stands as strata. Ie. Unit SE = SQRT(SE^2 + SE^2…). SE’s are weighted by stand area, if all stands have area. SE’s are unweighted if one or more stands are missing area.
