In this demonstration, see how STATISTICA’s “type ahead” feature recognizes functions and prompts for the necessary parameters. Furthermore, STATISTICA provides the option to automatically or manually recalculate all spreadsheet functions as the data change. Variables in STATISTICA Spreadsheets can be defined by formulas that support a wide selection of mathematical, logical, and statistical functions. This tutorial illustrates several of the data cleaning tools of STATISTICA. You can specify cases in two different ways, either temporarily, only for the duration of a single analysis, or more permanently for all subsequent analyses using the current spreadsheet.ĭata Cleaning is an important first step in Data Mining and general analysis projects. In this demonstration, see the extremely flexible facilities for case selection provided in STATISTICA. This makes it very easy to compare results of an analysis across different groups. With STATISTICA, you can generate output for each unique level of a By variable or unique combination of multiple By variables at the individual results level. By creating bundles, you can quickly and easily locate a subset of data in a large data file. With the Variable Bundles Manager, you can easily create bundles of variables in order to organize large sets of variables and to facilitate the repeated selection of the same set of variables. STATISTICA Projects provide the means to save your work and return to it later. A project is a “snapshot” of STATISTICA at the time it was saved: input data, results including graphs, spreadsheets, workbooks and reports, and data miner workspaces. This tutorial explains how projects are used. Run multiple copies of STATISTICA at the same time, run multiple analyses of the same or different kinds, run analyses on the same or different data files, or do all three. In this demonstration, see the benefits of convenient multi-tasking functionality in STATISTICA.
