1. A method of estimating an attribute of objects, comprising:

  • a. obtaining a first sample of said objects based on a first sampling distribution;

    b. obtaining a first estimate of said attribute based on said first sample;

    c. obtaining a second sample of said objects based on a second sampling distribution, where said second sampling distribution is different from said first sampling distribution;

    d. obtaining a second estimate of said attribute based on said second sample;

    e. determining a lower bound for a variance based upon each of the first sample and the second sample; and

    f. combining the first sample and the second sample using a variance value for each one of the first sample and the second sample that is equal to or larger than the lower bound for the variance for the first sample and second sample.
