con_threeletter_holland: Congruence Index according to Wolfe & Betz (1981)

Description

The function computes the three-letter congruence index according to Wolfe & Betz (1981).

Usage

con_threeletter_holland(a, b)

Arguments

a

a character vector with person Holland codes.

b

a character vector with environment Holland codes.

Value

a numeric with value for congruence.

Details

The function finds the congruence according to Wolfe & Betz (1981) between the three-letter Holland codes given in argument a, which is the person code, and argument b, which is the environment code. The Index as defined by Wolfe & Betz (1981) targets (only) three letters from the Holland code. The degree of congruence is output, according to its definition by Wolfe & Betz (1981), as a reciprocal value of a distance. This means, for example, that a value of '2' is the result for a perfect fit of two three-letter codes !
