Description
AUSPREADSHEET puts results from an analysis, by AUNBALANCED, of an unbalanced design into a spreadsheet. By default the results are from the most recent analysis by AUNBALANCED, but you use the SAVE option to specify the save structure from some other analysis.
The SPREADSHEET option specifies which pages of the spreadsheet to form, with settings:
aovtable |
analysis of variance table, |
|---|---|
effects |
estimates of effects, with their standard errors, t-statistics and probabilities, |
means |
tables of treatment means, |
semeans |
tables of standard errors of treatment means, |
sedmeans |
matrices of standard errors of differences of treatment means, |
esemeans |
tables of effective standard errors of treatment means, |
lsdmeans |
matrices of least significant differences of treatment means, |
replications |
replication tables of treatment terms, |
fittedvalues |
y-variate, fitted values and residuals. |
By default, SPREADSHEET = aovt, mean, sedm, repl, fitt.
To help avoid clashes between the columns of the spreadsheets if you want to save results from more than one analysis, the parameters MEANS, SEMEANS, SEDMEANS, ESEMEANS, LSDMEANS, EFFECTS, REPLICATIONS, RESIDUALS, FITTEDVALUES and AOVTABLE allow you to specify identifiers for the columns (or sets of columns) that will store the corresponding results in the current spreadsheet.
Tables of means are obtained from the AUKEEP procedure which uses the PREDICT directive. The first step (A) of the calculation forms the full table of predictions, classified by every factor in the model. The second step (B) averages the full table over the factors that do not occur in the table of means. The COMBINATIONS option specifies which cells of the full table are to be formed in Step A. The default setting, estimable, fills in all the cells other than those that involve parameters that cannot be estimated, for example because of aliasing. Alternatively, setting COMBINATIONS=present excludes the cells for factor combinations that do not occur in the data. The ADJUSTMENT option then defines how the averaging is done in Step B. The default setting, marginal, forms a table of marginal weights for each factor, containing the proportion of observations with each of its levels; the full table of weights is then formed from the product of the marginal tables. The setting equal weights all the combinations equally. Finally, the setting observed uses the WEIGHTS option of PREDICT to weight each factor combination according to its own individual replication in the data.
The LSDLEVEL option specifies the significance level (as a percentage) for the least significant differences; default 5.
You can save the data in either a Genstat workbook (.gwb) or an Excel spreadsheet (.xls or .xlsx), by setting the OUTFILENAME option to the name of the file to create. If the name is specified without a suffix, '.gwb' is added (so that a Genstat workbook is saved). If OUTFILENAME is not specified, the data are put into a spreadsheet opened inside Genstat.
Options: MEANS, SEMEANS, SEDMEANS, ESEMEANS, EFFECTS, REPLICATIONS, RESIDUALS, FITTEDVALUES, COMBINATIONS, ADJUSTMENT, AOVTABLE, RMETHOD, LSDMEANS, LSDLEVEL, SPREADSHEET, OUTFILENAME, SAVE.
Parameters: none.
Action with RESTRICT
If the Y variate is restricted, that restriction will carry over into the fitted-values spreadsheet.
