Alternative Outlier Model

!OUTLIER

The !OUTLIER qualifier invokes a partial implementation of research by Alison Smith, Ari Verbyla and Brian Cullis. With this qualifier, ASReml 3 writes
  • G-1u and G-1u/ sqrt(diag( G-1- G-1 CZZ G-1)) to the .sln file,
  • and R-1e/ sqrt(diag( R-1- R-1 WC-1W' R-1)) to the .yht file,
  • and copies lines where the last ratio exceeds 3 in magnitude to the .res file
  • and reports the number of such lines to the .asr file.

    This is definitely work in progress. It is not debugged for multivariate models or XFA models with zero PSIs, and has not been validated for other models.
