Using simulated data from a multivariate normal distribution with correlations between the dimensions. > data were simulated using a multivariate normal distribution (N = 20 million), where the three variables were standardized (mean of 0 and SD of 1). The correlations were specified as: intelligence with conscientiousness (−0.03), intelligence with emotional stability (0.07), and conscientiousness with emotional stability (0.42). Cases were classified into four categories based on z-scores across the three dimensions: notable (≥ 0.0 SD), remarkable (≥ 1.0 SD), exceptional (≥ 2.0 SD), and profoundly exceptional (≥ 3.0 SD).
