Updating Factor Analytic loadings


After ASReml calculates updates for variance parameters, it checks whether the updates are reasonable and sometimes reduces them over and above any STEPSIZE shrinkage. For factor loadings, the default behaviour is to shrink the loadings only in the first iteration if they appear large. This qualifier gives some user control. If it is specified without an argument, no (extra) shrinkage is allowed. Otherwise shrinkage is allowed in the first i iterations.
