iccde: Computation of the Double-Entry Intraclass Correlation

The function computes the profile similarity measure double-entry intraclass correlation. It is a more precise index of the agreement of two empirically observed profiles than the often used intraclass correlation or profile correlation. Profiles comprising correlations are transformed according to the Fisher z transformation before the index is calculated. In the case of score data with different scale formats (e.g., if the profile contains different IQ or a variety of personality tests), it is recommended to z-standardize the scores before entering into the function.
