Reordering Levels or Labels

Any analysis or calculation involving a factor will use the current factor level/label ordering. For example, if a table is calculated using one classifying factor then the first level/label of the factor will be used for the first row of the table, and so on.

By default, when a factor is created within Genstat the levels will be ordered numerically, and labels alphabetically. You can change the ordering of the factor levels or labels in the displayed output of your analysis by changing their association with the underlying ordinal values.

The table below shows a factor with four labels ordered alphabetically (the default). Another possible ordering for the labels could be from Zero to High, as shown below.

Ordinal Label
1 High
2 Low
3 Medium
4 Zero
