1. A method for excluding variations attributable to equipment from split analysis procedures, the method including: identifying one or more dependent variables related to at least one of a split analysis or an experiment to be performed; performing a test to ascertain whether or not a variation attributable to equipment exists with respect to any of the one or more identified dependent variables; if a variation attributable to equipment exists, constructing a target data set and a training data set, the target data set including the identified dependent variables and the training data set comprising any data set from which a statistical model may be constructed; identifying a signature for the variation attributable to equipment; selecting a statistical model based upon the identified signature; constructing the selected statistical model using the training data set to generate a statistical output; joining the target data set with the statistical output; and adjusting the identified dependent variables in the target data set using the statistical output.
