Method | Model | Detail |
---|---|---|
REG | Y = Xb + e | Ignoring population structure and familial relatedness, with no adjustment |
PC | Y = Xb + Qv + e | Top 10 eigenvectors from principal components analysis are used as the input of Q |
KIN | Y = Xb + Zu + e | Kinship matrix based on pedigree data is used as Z to define covariance structure of u |
PC-KIN | Y = Xb + Qv + Zu + e | Combining PC and KIN methods |
IBS | Y = Xb + Zu + e | IBS matrix based on genotype data is used as Z to define covariance structure of u |
PC-IBS | Y = Xb + Qv + Zu + e | Combining PC and IBS methods |
