How Do I Split a STATISTICA Datafile into Smaller Files?
Select Subset/Random Sampling from the Data menu to display the Create a Subset/Random Sampling dialog, where you can create a subset of your datafile based on the specified variables and either case selection conditions or random sampling. Once your selections have been made, a new spreadsheet with the requested subset is created, and you can continue the analyses using the subset of data. See Subset/Random Sampling for further details. Saving subsets. When you intend to save the subset, select either Save As or Save from the File menu to save the new spreadsheet. The original file is not in danger of being overwritten unless you use the same name. Permanent vs. temporary subsets. Subset creation is designed mostly to create permanent subset files, because in order to temporarily select a subset of data to be analyzed, the on-line Case Selection Conditions are more convenient to use.
