Biplot based on tester Stderr standardized data
From Models, select Scaling, then Within-tester Stderr Scaling.
GGE Biplot based on this model may be called GGE3 biplot. Sample biplot is not available for non-replicated data (e.g. the two-way data on this page) as it is not possible to calculate the standard errors.
The interpretation of a GGE3 biplot is the same as for a GGE1 biplot except that possible heterogeneity among testers are removed. However, it is possible that the importance (discriminating power) of testers with very small stderr values may be over-emphasized.
