This page describes the additions and changes to procedures and directives in Release 24.2
1. Highlights
● 11 new procedures
● Procedures have been updated to use CycDesigN 8, and now form improved p-rep designs (CDBPREP, CDRCPREP, CDNBLOCKDESIGN, CDNROWCOLUMNDESIGN)
● The automatic REML procedures can now fit two-dimensional spline models (VABLOCKDESIGN, VAROWCOLUMNDESIGN, VASERIES, VAMETA)
● Voronoi tessellations and Delaunay triangulations (TRIANGULATION)
2. What’s new
2.1 Directives
None.
2.2 Procedures
ALARM plays a sound.
CDBPREP constructs a partially-replicated block design using CycDesigN.
CDRCPREP constructs a partially-replicated row-column design using CycDesigN.
CDNUSERMENUS installs or removes menus, to run CycDesigN, in the User menu on the Genstat menu bar.
FVASPLINESPECIFICATION forms specifications to form two-dimensional spline models by VASPLINE.
RGBNAME gets the name of the nearest colour to an RGB colour.
TRIANGULATION calculates a Voronoi tessellation or a Delaunay triangulation of the x-y plane, and plots these as graphs.
VASPLINE forms two-dimensional spline models for use by the automatic REML procedures.
VASTATUS displays the contents of a model-definition structure defined for a REML analysis.
VA2BLUPS modifies a model-definition structure for a REML analysis to estimate BLUPs instead of BLUEs.
VFSPLINE adds a two-dimensional spline model to a model-definition structure for a REML analysis.
2.2 Functions
None.
3. What’s changed
Most of the changes are compatible with Release 24.1, the previous release. There are a few commands, however, where new options or parameters have been renamed or inserted into the existing lists. These may cause problems in statements where option or parameter names have been omitted or abbreviated (see Section 1.7.1 of Part 1 of the Guide to the Genstat Command Language for details). To avoid any difficulty, the name of the option/parameter after the new option/parameter should be given explicitly, and not abbreviated to fewer than four characters.
Any command, where changes in Release 24.2 may cause incompatibilities in existing programs, is marked in Sections 3.1 and 3.2 by the symbol †. The full details are given in Section 3.4.
3.1 Directives
VCYCLE now has a SAVE option to save the current settings of the aspects of the REML algorithm that it controls.
3.2 Procedures
CDNBLOCKDESIGN and CDNROWCOLUMNDESIGN updated to use CycDesigN 8.
CHISQUARE can now suppress messages.
DBIMPORT can now load extra details for the columns.
DDESIGN and DHEATMAP now allow you to control the orientation of the y-axis.
FPLOTNUMBER has a new PRINT option to display the plot number in a row × column grid, and new ROWS and COLUMNS parameters to save the row and column coordinates.
IMPORT can now read the meta-data from a Genstat trial (.TRL) file.
KRUSKAL can now print and save the results of Dunn’s test.
NLAR1 can now fit emax and gemax models.
SDISCRIMINATE now has a TITLE option that can specify titles for the plots.
VABLOCKDESIGN, VAROWCOLUMNDESIGN, VASERIES and VAMETA can now fit two-dimensional spline models.
3.3 Functions
None.
