Major job qualifiers


Qualifiers are described in 4 sections based on frequency of use.
  • general syntax
  • The qualifiers defined on this page are
  • !CONTINUE, !CONTRAST, !DDF, !FCON, !MAXIT, !SUM and XYplots ( !X !Y !G !JOIN )
  • Occasional qualifiers include !ASMV, !ASUV, Spatial arrangement ( !COLFAC, !ROWFAC, !SECTION, !GKRIGE ), ANOVA qualifiers ( !FAMILY, !GROUP, !MBF, !SPLINE, !SUBSET ), graphics qualifiers ( !DISPLAY, !NODISPLAY, !EPS, !WMF ), missing values in design variables ( !MVINCLUDE, MVREMOVE ), convergence rate ( !STEPSIZE ) and setting prediction points ( !PVAL )

    Common qualifiers

  • !CONTINUE requests that a job be run using estimates of the variance parameters obtained in a previous run and held in the .rsv file
  • !CONTRAST is used to construct a contrast among factor levels for subsequent inclusion in the model.
     !CONTRAST Nlin Nitrogen  {-3 -1 1 3}/10
  • !DDF i gives the user some control of the calculation of the denominator degrees of freedom. The ASReml default action depends on the size and nature of the job.
    !DDF -1 suppresses calculation of the denominator degrees of freedom (and consequently the calculation of significance probablities) for F-statistics reported in the ANOVA table.
  • !FCON requests ASReml report Conditional F statistics as well as the standard incremental F statistics be reported in the ANOVA table.
  • !MAXIT n sets the maximum number of REML iterations.
  • !SUM requests ASReml generate an expanded set of statistics descriptive of the fields in the data file.
  • XY plots requests ASReml display plots of the data variables. Multiple plots are permitted.
