Whats New in Release 2

Critical Changes in Behaviour

Generally we seek to maintain upward compatability so that ASReml 1.00 code will continue to run. However, to deliver improved facilities, some changes to behaviour are unavoidable.

!CYCLE

The !JOIN qualifier is no longer required. More?

!D transformation.

The !D transformation dropped records based on a logical test against the value in the test field. It always dropped records which were missing. A new form, !DV has been created which does not drop records with a missing value as the test field unless the test value is asterisk. I.e. !DV * discards records with a missing value in the test field.

Loadings updates

The default updates for factor analytic loadings have changed which will generally change the iteration sequence for these models.
