con_n3_holland: Congruence Index according to Joerin Fux (2005)

Description

The function computes the congruence index according to Joerin Fux (2005).

Usage

con_n3_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 Joerin Fux (2005) between the up to six-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 J<U+00F6>rin (2005) targets (only) three letters from the Holland code. The degree of congruence is output, according to its definition by Joerin Fux (2005), as a reciprocal value of a distance. This means, for example, that a value of '3' is the result for a perfect fit of two three-letter codes !
