Sampling error for a whole inventory, not just per stand

    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.

    Uh Oh. I'll email you a remote session.

    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.Here are some good references:Freese, F. 1962. Elementary Forest Sampling. P30. Bell, J. 1992. Inventory and Cruising Newsletter.

    If I unselect the stands and only select unit, I get empty reports for stand summary and Stand Tables.Now that everything is unselected I can't select them again. No combination of left/right clicks or Ctrl/shift/alt will get me back to blue.In the process somehow it created a duplicate set of stands and I deleted them…. Closed and open the field data tab and now everything is gone.Ugh.
