EFAM: A FORTRAN IV Program for Correlation Coefficients between Variables of more than One Scale Type

Uppsala University, Uppsala, Sweden

Jan Vegelius

Uppsala University, Uppsala, Sweden

A program for computing correlation coefficients of variables from different scale types is presented. The computations are based on the concept of the E-correlation family of coefficients. Such a general coefficient is invariant over permitted transformations of the variables for their respective scale types. The program EFAM is able to consider the E-correlations from interval, ordinal, and nominal scales.
