Select Neighbor Markers with strongest LD within Baseline Unit Select this option to select the strongest LD markers with the target marker with missing genotype. The selection of markers takes place among markers in the same region defined by values specified using either the Marker Units or Annotation Location Variable Units options. If either option is set to zero, the section is among all markers. When this option is selected, the LD-kNNi method is applied to impute missing marker genotypes. Otherwise, the kNNi method is applied to impute missing marker genotypes. To Specify This Option: Click the check box.
