Displays further output from a REML analysis.
Options
PRINT = string tokens |
What output to present (model, components, effects, means, stratumvariances, monitoring, vcovariance, deviance, Waldtests, missingvalues, covariancemodels); default mode, comp, Wald, cova |
|---|---|
CHANNEL = identifier |
Channel number of file, or identifier of a text to store output; default current output file |
PTERMS = formula |
Terms (fixed or random) for which effects or means are to be printed; default * implies all the fixed terms |
PSE = string token |
Standard errors to be printed with tables of effects and means (differences, estimates, alldifferences, allestimates, none); default diff |
CFORMAT = string token |
Whether printed output for covariance models gives the variance matrices or the parameters (variancematrices, parameters); default vari |
FMETHOD = string token |
Controls whether and how to calculate F-statistics for fixed terms (automatic, none, algebraic, numerical); default auto |
Parameter
| REML save structures | Save structure containing the details of each analysis; default is to take the save structure from the latest REML analysis |
|---|
Description
The VDISPLAY directive allows further output to be produced from one or more REML analyses without having to repeat all the calculations.
Information from a REML analysis can be stored using the parameter SAVE in the REML statement for use in the SAVE parameter of VDISPLAY. Several SAVE structures can be specified, corresponding to the analyses of several different variates. By default, the save structure for the last y-variate analysed is saved automatically and used by VDISPLAY.
The options of VDISPLAY are the same as those that control output from REML: PRINT, PTERMS, PSE, CFORMAT and FMETHOD, plus the CHANNEL option which allows output to be directed to another output channel or into a text structure. The available settings of PRINT are identical to those in REML. For example, the commands
VCOMPONENTS [FIXED=Nitrogen*Variety] RANDOM=Block/Wplot/Splot
REML [PRINT=model,wald,components] Yield
VDISPLAY [PRINT=effects]
print the effects for the fixed terms after the analysis, without having to re-run the algorithm.
Options: PRINT, CHANNEL, PTERMS, PSE, CFORMAT, FMETHOD.
Parameter: unnamed.
