    Brad Walter asked this very good question in email on June 15 2014:

    "David I have a question about ANOVA and AOV in VStar. The sample sized per
    bin are different. What are you doing to correct for that. The "normal"
    ANOVA formulas assume equal sample size. That is almost never the case in
    astronomy. We use equal time duration bins but over long periods of data.

    See the cautions near the bottom of the following:
    http://en.wikipedia.org/wiki/Analysis_of_variance . When I took the
    Statistics course to become acquainted with R I found another web site that
    went into the corrections in detail but I can't find where I saved the
    reference. I am just curious what method you use."

    One possible implication is the need for some kind of date compensated AoV.

    Note that Brad's comment above also applies to ANOVA in general.
