The software performs parallel analysis to facilitate factor analysis done in parallel.

ROC Analysis is a Macintosh program that generates the Receiver Operating Characteristic (ROC) curve and calculates the Area Under the ROC Curve (AUC) using a nonparametric method. The software is written in RealBasic and operates independently.

The software offers tests for regression slope and intercept to analyze test bias. It is a useful tool for identifying any potential bias in test scores.

Pairwise Tests software allows users to conduct three tests - simple Bonferroni, Holm's sequential Bonferroni, and Benjamin & Hochberg's False Discovery Rate - in order to control experimentwise error rates. The program has been developed using RealBasic.

rDiff software, developed in RealBasic, determines the reliability of difference scores taking into account the reliability and correlation of two tests.

Standard Score Converter software enables conversion between standard scores like z, T, deviation IQ, NCE, percentile, etc. It is coded in RealBasic for its source.

This Macintosh application calculates three indices providing factorial invariance. It operates as a standalone software and is compatible with all Macintosh platforms.

ASCA Scoring is a dedicated Mac application designed for scoring the Adjustment Scales for Children and Adolescents. This standalone software is optimized for ease-of-use and accuracy, ensuring reliable scoring for healthcare professionals, clinicians, and researchers.
