The calculations of the last section do not illustrate the effects of value dependence. Certain dependence chains involve adjustments in both blocking and weighting statistics since both reliability and coincidence are affected. To illustrate we proceed as we did in ¶ 6-2.1 when we calculated the preliminary values in table 1. Just as with the presence dependence adjustments, in a dependence chain of three fields, there are four kinds of comparisons that make sense. If the three fields are blocking fields, only one combination applies: they must all be present and agree. When some are blocking and others are weighting fields, the combinations apply which are present and agree in blocking so long as they are present in weighting.
