We will first derive the equations needed to calculate the probability of a weight being matched and of being unmatched with a review of the adjustments required. Probability calculations must take account of presence dependence. Each comparison weight comes from a particular combination of field weights — each field being in agreement, in disagreement, or missing. We finally consider the number of calculations that are required.
