STATISTICA(R): Demonstration Program Welcome to the STATISTICA version 5.5 Demonstration Program. This Demonstration Program is not a "self-running" demo; it is a program with many features of the Basic Statistics module of STATISTICA and it allows you to run your own analyses and produce customized graphs. Note that this Demonstration Program came with several example data files (located in the EXAMPLES subdirectory inside the Demonstration Program directory) on which you can perform various analyses and create different kinds of graphs. To run a 'Guided Tour' (requires a sound card) select the respective option from the Help menu. QUICK REFERENCE ELECTRONIC MANUAL: Press F1 at any point in the program to access the comprehensive Electronic Manual. EXAMPLE: CORRELATIONS After starting the program, the last-used data file is automatically opened (when you start the Demo program for the first time, the data file ADSTUDY.STA will open). Select Correlation Matrices from the start up panel (the same selections are available from the pull-down menu Analysis). The Correlation dialog will appear. Press the first button (One variable list (square...)) to choose the variables for the correlation matrix; for example, highlight 10 variables in the list: MEASUR1 through MEASUR10 and click OK. Then, click OK to see the default output: a Scrollsheet showing the correlation matrix. The numbers in the correlation matrix represent relations between the variables; the higher the absolute value of a correlation coefficient, the stronger the relation between the two respective variables. To see graphs related to a particular correlation coefficient, point to that coefficient with the right-mouse button. A "flying menu" will pop-up. Select the first option in the menu: Quick Stats Graphs, and then, from the list of "quick" graphs, select the first one: a Scatterplot. The graph will appear on the screen. Now you can explore the other "quick" graphs which visualize the variables from the correlation matrix. You can also return to the previous dialog to review other options (press the Continue button on the correlation matrix Scrollsheet or the "floating" Cont button near the bottom of the STATISTICA window). For a comprehensive selection of graphs, try the pull-down menu Graphs or the toolbar button Graphs Gallery. TOOLS "Flying menus." Point to any object on the screen and press the right-mouse-button to bring up a context-sensitive "flying menu" of options related to the object. Try it for a spreadsheet cell -- the options will include a selection of relevant graphs, formats, recoding, etc. In graphs, the "flying menu" options allow you to quickly customize the selected object (e.g., a scale, title). Toolbars. The most common tools are accessible from the toolbars. The toolbars change when you switch between output windows (e.g., graphs have different toolbars than spreadsheets). To review the short toolbar-button descriptions on the status bar (at the bottom of the window), keep the selected toolbar button pressed; then, release the mouse outside the toolbar to release the toolbar button without invoking its function. DATA Data files. STATISTICA data files are organized into cases (rows in the spreadsheet) and variables (columns in the spreadsheet). Cases are like records in data base management files and they consist of a number of variables (e.g., each case may represent one patient in a medical study). Variables (columns) are like fields in data base management files (e.g., each variable may represent one type of measurement, such as the cholesterol level, blood pressure, etc.). Variables. To review or edit the specifications of a variable, double-click on the respective column name in the spreadsheet. Text values; value labels. In STATISTICA, all values can simultaneously have numeric and text identities (e.g., 1=MALE, 2=FEMALE). Switch between displaying the two by pressing the spreadsheet toolbar ABC button. All values can also have long labels; to review/edit the labels for the highlighted variable, press the toolbar ABC/123 button. Subsets of cases. To specify a subset of cases to be included in (or excluded from) an analysis, double-click on the clickable Sel: OFF field on the status bar (at the bottom of the STATISTICA window). FLOW OF INTERACTIVE ANALYSES Self-prompting dialogs. To perform an analysis, select it from the startup panel (or the pull-down menu Analysis or Graphs). If you are not sure what to select in a dialog, press OK; then, if necessary, STATISTICA will request that you make additional selections. Queues of Scrollsheets and graphs. The Scrollsheets (output tables with built-in customization and data visualization facilities) and graphs are displayed in queues of windows of a fixed length (by default, 3 windows in each queue) and they are closed on a first-in-first-out basis. You can customize this system using the pull-down Options or Window menus. Text and graphics reports. In addition to the printer and disk file output, the content of all Scrollsheets and graphs can be directed to a report window; double-click on the Output: OFF field on the status bar (at the bottom of the window) to review some of the relevant options. CUSTOMIZATION OF THE USER-INTERFACE STATISTICA supports a selection of user-interfaces (various interactive interfaces, internal macros, command languages, macros written in other applications which support DDE). Practically all aspects of the user-interfaces are customizable. For example, to review some of the output reporting options, double-click on the Output: OFF field on the status bar (at the bottom of the window) or use the pull-down menu Options. GRAPHS Types of graphs. Many specialized graphs are part of the output from respective analyses and they are automatically generated or are available from the respective Results dialogs and/or Scrollsheets. The "general purpose" graphs are available from the pull-down menu Graphs or the Graphs Gallery (accessible by pressing a toolbar button). In that menu: The Stats Graphs options offer hundreds of types of pre-defined statistical graphs produced from raw data; The Quick Stats Graphs (also accessible from "flying menus" and all toolbars) offer a selection of the most often-used types of Stats Graphs; they are "quick" in the sense that they do not require going through any intermediate dialogs; they do not even require selecting variables because the variables indicated by the highlight position in the current spreadsheet or Scrollsheet are automatically used; The Custom Graphs options (also accessible from "flying menus" and all toolbars) allow you to convert any combination of numbers from rows and/or columns (and their subsets) in the current spreadsheet or Scrollsheet into graphs; The User-Defined Graphs offer types of graphs which were not available as pre-defined graphs but were "constructed by the user" and added to the menu or floating toolbars for repeated use; The Blank Graphs create "empty" graph windows where other graphs (and/or drawings, diagrams, and other artwork) can be pasted or linked/embedded; the same effect can be achieved by starting with an existing graph and extending its margins to make room for other objects. Customization of graph layout. The "flying menu" of global graph customization options can be popped up by pressing the right-mouse-button anywhere on the "empty" outside background of the graph. The most commonly-used global customization options are included in the General Layout dialog accessible from that menu (see the first option of the menu) or by double-clicking anywhere on the "empty" outside background of the graph. Customization of graphic objects. The "flying menu" with customization options applicable to a graph object (e.g., scale, title, gridlines, markers) can be quickly accessed by pressing the right- mouse-button on the object, e.g., on a graph scale. The most commonly-used customization dialog for an object (e.g., for a marker -- the Patterns, colors, and sizes dialog) can be accessed by double-clicking on the object. Drawing, zooming, etc. If you press one of the toolbar buttons to enter a graph drawing, zooming, inserting, resizing, etc. mode, press the wide arrow button on the graph toolbar (or press the Esc key) to return to the default pointing mode. To edit an existing custom-drawn object (e.g., a freehand line or rectangle), click on it with the mouse -- then, you can resize it (by dragging the black resizing squares), or change its color, pattern, etc. (by using the respective toolbar buttons). Freehand lines support the "second- level" line shape editing mode: the editing squares will appear in every point where the line changes its direction -- you can now drag any one of them with the mouse to modify the local shape of the drawing (to edit fine details, zoom on the object with the toolbar magnifying glass (zoom +) tool).
