Overview
STATISTICA is a comprehensive, integrated statistical data analysis, graphics, data base management, and custom application development system featuring a wide selection of basic and advanced analytic procedures for science, engineering, business, and data mining applications. The system includes not only general-purpose statistical and graphics procedures, but also comprehensive implementations of specialized modules (e.g., for social scientists, biomedical researchers, or engineers). All modules are available to the user as part of an integrated package that can be controlled with a selection of alternative user-interfaces, including comprehensive, Wizard-aided programming languages that can be used to build custom extensions or to integrate STATISTICA with other applications or computing environments. One can hardly imagine a user who would need all statistical and graphics procedures offered in STATISTICA, however, the experience of many satisfied users of the package indicates that accessibility of analytic and graphics techniques from outside one’s traditional area (offered by the exceptional comprehensiveness of STATISTICA) encourages new, creative ways in which one can verify hypotheses and explore data.

Complete integration with the Windows system
STATISTICA offers comprehensive support for the Windows environment and it creatively uses the advanced options of the Windows (95 and NT, also where applicable, compatible with 3.1) system to enhance the performance of the program and facilitate the user's interaction with the computer. The following list of features summarizes the major aspects of this integration.

Clipboard (graphics)
STATISTICA offers flexible multi-format graphics Clipboard support with convenient facilities for on-screen rearrangement of graphic objects, and for copying/moving them between windows (including options to copy and paste either specific logical objects, such as free-hand drawings, embedded graphs, or rectangular graph regions "cut across objects," a variety of options to control the status of pasted objects, e.g., Paste Replace, locking, proportions, object mapping mode, etc.), a Clipboard-based, handy Screen Catcher tool (that can also be used outside STATISTICA); specialized reconfiguration options useful for producing camera-ready artwork or high-resolution negatives (see also the section on STATISTICA OLE support).

Simultaneous OLE Client and Server mode
Finally, if you insert STATISTICA's objects into STATISTICA's documents, the program will act simultaneously as a server and client, and then a variety of specialized extensions to the OLE mechanism will be available to facilitate customization of the compound graphics documents. For example, graph mapping settings can be adjusted and tools are provided to interactively adjust the sizes of fonts and markers in all graphs inserted into a master graph by pressing buttons on a toolbar. The Multiple-Graph AutoLayout Wizard can be used to guide you step by step through the process of creating perfectly aligned multiple graph displays.

DDE/API
STATISTICA supports the Windows DDE/API interface standards allowing the user to control STATISTICA from within other Windows programs, such as MS Excel or MS Visual Basic.

Extended user-interface standards
STATISTICA supports an extended set of Windows user-interface standards (such as interactively adjustable MicroScrolls for quick value entry, AutoFill block extensions, variable-speed scrolling, Drag-and-Drop file opening, ToolTips, floating toolbar docking, and dozens of others). Moreover, where applicable, STATISTICA makes Windows 95/NT conventions operational even in the Windows 3.1 environment.

Compatibility with Windows DLL procedures
From within the STATISTICA application, you can call external Windows procedures such as, for example, routines from commercial or public domain libraries of computational algorithms or other procedures. Those external procedures can be used to process STATISTICA data or results (STATISTICA BASIC provides a convenient interface for incorporating other Windows programs into your custom STATISTICA BASIC programs.).

Statisticas Speed
The STATISTICA system offers unmatched speed of numerical, graphics, and data base management operations. It includes not only hundreds of numeric processing (and graphics) speed optimization procedures but also a system of low-level input/output and memory management optimizations (including a proprietary screen redraw and "region selection" system which refreshes, redraws, and highlights complex sets of graphical objects at speeds limited only by the hardware of the computer (and the drivers), additionally contributing to the program's overall "responsiveness"). For example, on an "old" 486/33 computer:

Statisticas Precision
Not only were all computational algorithms of STATISTICA designed to yield maximum accuracy, but a number of innovative technologies (e.g., "quadruple precision") were introduced in most of the low-level computational engines of the program in order to overcome the limits of "floating point" math (which are common to many spreadsheet, math, and statistics programs). As a result, STATISTICA offers an unmatched level of accuracy and can handle even extreme cases of small relative variance and other highly demanding benchmarks of numerical precision. Due to the other unique feature of STATISTICA -- its interactive, user-controlled display formats supported for all numerical output -- the presentation of numerical results can be interactively adjusted allowing you to take advantage of the numerical accuracy delivered by the program.

Graphics facilities in STATISTICA
Graphics facilities in STATISTICA combine an extremely wide selection of scientific and technical charts (featuring built-in analytic facilities) with customization, drawing, and multigraphics management capabilities that are usually found only in designated presentation graphics and drawing programs. STATISTICA offers hundreds of types of 2- and 3-dimensional graphical displays, including 2- and 3-dimensional ternary graphs, special 4-dimensional graphs, multidimensional graphs, categorized multigraphs, matrices of graphs, icons, tessellations, layered graphs, spectral 2- and 3-dimensional graphs, compound graphs, and many other specialized procedures. Also, flexible and very easy to use facilities are provided to custom-design completely new types of graphs and add them permanently to the menu or floating toolbars.

Selection of data management facilities
STATISTICA includes an integrated, comprehensive data base management system that provides a selection of unique, specialized facilities designed to manage data sets for statistical analyses. An extremely large selection of options (including a spreadsheet of practically unlimited capacity with a full selection of Drag-and-Drop and AutoFill facilities, comprehensive data transformation and restructuring options, import/export, and data verification/cleaning) can easily be supplemented by user-specified procedures that can be added to the system for repeated use.

Basic statistical exploratory methods
The basic statistical exploratory methods include such techniques as examining distributions of variables (e.g., to identify highly skewed or non-normal, such as bi-modal patterns), reviewing large correlation matrices for coefficients that meet certain thresholds (see example above), or examining multi-way frequency tables (e.g., "slice by slice"systematically reviewing combinations of levels of control variables).

Multivariate exploratory techniques
Multivariate exploratory techniques designed specifically to identify patterns in multivariate (or univariate, such as sequences of measurements) data sets include: Cluster Analysis, Factor Analysis, Discriminant Function Analysis, Multidimensional Scaling, Log-linear Analysis, Canonical Correlation, Stepwise Linear and Nonlinear (e.g., Logit) Regression, Correspondence Analysis, Time Series Analysis, and Classification Trees.

Programming with STATISTICA BASIC
STATISTICA BASIC is a simple to use but powerful programming language which can be used for a variety of types of applications ranging from simple data transformations (e.g., whenever you need to do more than can be done using the spreadsheet formulas) to building custom, complex, extensions to computational, graphics, and data management procedures of STATISTICA.

New in Statistica 7

  The individually tailored interface allows for more efficient management of output. "Quick Tabs" allow for quick access to critical results, while "Advanced Tabs" give users access to more specialized tools and freedom to further explore and visualize their data.
• Convenient workbooks and reports
  Output options have been significantly expanded to include a flexible Workbook and Reporting functionality capable of efficiently managing practically unlimited numbers of active, multimedia documents (both STATISTICA native and ActiveX documents), organized hierarchically and optionally linked together.
• Full Web-enablement options
  Both input and output can be handled via the Internet. Users can automatically publish their output on the Web in easily navigable reports with embedded objects and instruct STATISTICA, through their browser, to perform specified analysis and display their output. STATISTICA's computational and data querying power can be accessed from practically any computer in the world that is connected to the Web.
• Compatibility/programmability
  Built-in, industry standard Visual Basic scripting language allows programmers to access directly every aspect of the program to automate routine tasks or develop elaborate custom applications.
• New Stats
  General Discriminant Function Analysis, Enhanced Classification and Regression Trees, Nonlinear Estimation Routines, and Advanced Principal Components and Classification Analysis have been added to the already comprehensive selection of statistical techniques.
• Graphics
  Enhanced graphics technology with hundreds of new options, an array of fully automated graphics styles, and advanced support for active compound graphs gives users more visualization and exploratory functionality. For example, a new unique "interactive 3D explorer" tool allows users to brush or zoom precisely selected subsets of data by "slicing" 3D space (with the mouse).
• Speed
  STATISTICA 6 features a new generation of optimizations that improve even the fast analysis speeds of the previous version (STATISTICA 5) which was one of the fastest applications available on the market. These optimizations are especially useful when accessing enterprise databases and analyzing large amounts of information.
• Unlimited capacity
  Virtually all system limitations from previous versions have been removed. For example, multiple copies of STATISTICA can now run simultaneously, each processing multiple and concurrently open data files. An unlimited number of variables can be stored in the new system data files and text values, labels, variable names and case names can store virtually unlimited number of characters.
• Optimized access to remote databases
  Enterprise versions of STATISTICA feature new technology to efficiently query and access remote databases of virtually unlimited size without having to import subsets of these data or create their local copies. This is especially useful for processing extremely large databases for data mining.
