ASReml 2 features

Improved license management

  • The license management has been upgraded

New environments and add-in modules to run ASReml

  • ASReml-W a new improved windows client to run ASReml
  • ASReml-S an add-in module to run ASReml in S-plus
  • ASReml-R an add-in module to run ASReml in R

Expanded ANOVA options

  • The Analysis of Variance table has been expanded to optionally include a conditional Wald F-statistic and in most cases, denominator degrees of freedom can be calculated allowing significance testing of the F-statistics.

Command line features

  • Ability to generate a template .as from command line.
  • New command line options.

Field Definition qualifiers

  • No limit on storage of alphabetic factor labels.
  • Ability to sort factor levels.
  • Ability to read data and time fields.
  • New transformations.

Pedigree and GIV files

  • New .grm file extension can be used to supply an univerted matrix in sparse format which will be automatically inverted by ASReml.
  • More efficient formation of the A-matrix (substantial reduction in time forming the matrix if many animals without progeny).
  • New pedigree processing options.

Reading Data

  • Columns or rows can be combined from different files.

Datafile line qualifiers

  • Datafile line qualifiers may also be defined using an environment variable.

Linear Model Specification

  • Includes facilities for fitting the family of Generalized Linear Models.
  • Facilities for fitting Generalized Linear Mixed Models.
  • New Model terms available

Predict

  • Can control the order of terms within the prediction table.
  • Facility to plot predictions.

Variance structures

  • Autoregressive models have been extended to include AR3 and SAR2.
  • The Matern class of isotropic covariance models is now available.

Output

  • Plot of the Residuals vs Predicted values is added to the .res file with other residual statistics.
  • A variogram is now reported for non-regular spatial data residuals.
