Tip of the week

Split your datafile

You can split your datafile using a categorical variable. All tests and/or graphs are then performed for the individual categories of the split variable. Select 'Split Data' from the menu and indicate one or more split variables.

Define value labels

Brightstat works best with all your variables in number format. However, for categorical variables you can define value labels. These will be used instead of the number values in output tables and graphs. In the data or the variables window select 'Define Value Labels' from the menu.


2015-07-02

Sort data

You can sort your data by clicking on the header cell of the desired variable column in the data window

Save and reuse graph templates

In the graph edit dialogue box select 'template' and save your graph as template file. You can apply this template to all graphs of the same type, e.g. a scatterplot template can only be applied to scatterplots. Until now, templates are not stored in the database, they are active only during your current session. However, subscribers can save an output with graphs and reuse the graphs as templates in later sessions.
