    Smile Statistical method

    What is the method called when you look for stability in process classification when you use
    subsets of the data? The subsets are selected in a randomized order of equal sample size.
    Any help will be greatly appreciated. Thanks.

    Not quite sure what you are trying to do, but could it be a variant of the bootstrap (or jacknife, or crossvalidataion)?

    If I understand your question correctly, the technique you are describing is known as k-fold cross-validation, which is explained here:
