Estimated correlation distributions, mixture model. The correlation distribution smoothed, as a mixture. The black line is the estimated mixture distribution; the red and green are the estimated mixture components. For comparison, the orange line is an nonparametric smooth density estimate. The rug ticks are observed correlations, and the tick colors indicate group assignment by maximum posterior probability. Correlations greater than 0.217 have Pr(mixture component #2) > 0.5, and corresponding tick are colored green for component #2.
