Details

The function finds the congruence according to Wiggins & Moody (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 Wiggins & Moody (1981) targets (only) three letters from the Holland code. The degree of congruence is output, according to its definition by Wiggins & Moody (1981), as a reciprocal value of a distance. This means, for example, that a value of '8' is the result for a perfect fit of two three-letter codes !
