Table 3 True versus estimated (hat) parameters in Simulation II. π k is the mixing proportion in the k th cluster, and μ k and σ 2 k are the mean and variance of k th mixture component, respectively. Values expressed in units of phenotypic standard deviation
Cluster1 | Cluster2 | |
|---|---|---|
π k | 0.800 | 0.200 |
\( {\widehat{\pi}}_k \) | 0.912 | 0.089 |
σ 2 k | 0.023 | 0.360 |
\( {\widehat{\sigma}}_k^2 \) | 0.251 | 0.382 |
