Table 2. The eight tests that were evaluated in the simulation studies. FVH: foreground variance heterogeneity (i.e., variance effects at the QTL). BVH: background variance heterogeneity.
| Category | Test | Description |
|---|---|---|
| mQTL | SLM | Conventional test of mean differences; allows neither FVH nor BVH |
| mQTL | CaoM | Allows FVH, but not BVH |
| mQTL | DGLMM | Allows FVH and BVH |
| vQTL | Levene’s test | Conventional test of variance differences; detects FVH, does not allow BVH |
| vQTL | CaoV | Detects FVH, does not allow BVH |
| vQTL | DGLMV | Detects FVH, allows BVH |
| mvQTL | CaoMV | Detects FVH, does not allow BVH |
| mvQTL | DGLMMV | Detects FVH and allows BVH |
