data in a field having a certain value or range of values
only on condition that data in a certain other field has a certain value or range of values; v.
d. complicates the simultaneous use of both field weights in probabilistic
record linkage without
adjusting the measured coincidence value.
For example, the child's surname
(patronymic) of "Nielsen" or "Nielsdatter" (or their variations) depends on the father's given
name being "Niels." (or one of its variations.) The choice of given name for a child (its
gender) usually depends on the child's sex. The code assigned to a name depends on its spelling.
This is an example of "natural" v. d.; the assignment of the same name codes for different spellings of the same name is an example of
"constructive" v. d. (Cf. presence dependence,
dependency chain, chain (2).) [Cf.
