Transcription

1 SPSS Statistics 17.0 New capabilities What s New in SPSS Statistics 17.0 Recognizing the increasingly critical role of analytics in helping organizations reach their goals, SPSS Inc. has made significant improvements to the suite of powerful but easy-to-use statistical software products that had served the needs of tens of thousands of people in business, government, academia, and research since SPSS Statistics 17.0 provides new and enhanced capabilities to support you throughout the analytical cycle and ensure that your organization can more easily make decisions based on reliable data analyses. In this release, you ll find: n Improved tools for research and reporting n Easier ways for beginners and generalists to perform analysis, along with new functionality for advanced users and statistical programmers n Greater support for enterprise integration and the deployment and management of analytical assets All new features are available on the Microsoft Windows, Apple Mac OS, and Linux platforms.* And, in this release, those using SPSS Statistics on the Mac OS and Linux platforms can connect to SPSS Statistics Server, with appropriate licensing. This improves analytical performance, facilitates the management and deployment of analytic results, and provides IT with the necessary tools for integration, configuration, and maintenance of a client/ server deployment of SPSS Statistics. The SPSS Statistics Adapter is now also available to users of SPSS Statistics 17.0 on Mac OS and Linux, allowing organizations with mixed desktop environments to give all SPSS Statistics users access to the features and services available in SPSS Predictive Enterprise Services. (For more information about this advanced platform for managing, automating, and deploying analytical assets, go to Improved tools for research and reporting Researchers benefit directly from the new research and reporting features available in SPSS Statistics Multiple imputation of missing values One challenge survey researchers and others often encounter is missing data. Now, using SPSS Missing Values 17.0**, you can impute missing values in either categorical or continuous variables by multiple imputation. You ll obtain more accurate standard errors and significance levels than if data were imputed using a single imputation method, and gain a clearer picture than if you had ignored missing data in your analysis. Multiple imputation in SPSS Missing Values conducts imputation using the monotone or fully conditional specification methods. You can also have the most appropriate method selected automatically. Codebook creation In SPSS Statistics Base, survey researchers will be able to automatically create a codebook describing their dataset, eliminating the time-consuming task of creating one manually. The codebook contains dictionary information such as variable names, variable labels, value labels, missing values, and frequencies, allowing the user to easily communicate the results of a survey or questionnaire to anyone. * Amos 17.0, SPSS Viz Designer, and SPSS Exact Tests 17.0 are only available on the Microsoft Windows platform, and the exchange of data with SPSS Inc. s Dimensions family of survey research products is supported only on the version of SPSS Statsitics 17.0 that operates on Windows. **This module was formerly known as SPSS Missing Value Analysis.

2 More control when exporting to Microsoft Office New to SPSS Statistics 17.0 is more control at the time of export over wrapping and shrinking of tables for placement in Microsoft Office products; you can also export to existing Microsoft Excel spreadsheets. Export options can be controlled via the export interface in SPSS Statistics or via the syntax command language, allowing users to create automated export formatting for production jobs. Because you won t need to format SPSS Statistics tables manually in Office, you can create presentation-ready reports far more quickly. Nearest neighbor analysis This procedure enables analysts to use SPSS Statistics Base to quickly link cases to nearest neighbors to help group valued customers and identify competitors. It can be used in marketing, in clinical studies to select control cases that are similar to clinical cases, and in many other applications. Model Viewer integration provides users with greater insight into the analysis. Other enhancements to statistical procedures in this release include the ability to choose aggressive or conservative rounding in the COMPUTE procedure, which enables researchers to reproduce results from prior versions of SPSS Inc. software. Plus, refinements to a number of procedures in SPSS Statistics Base and in SPSS Advanced Statistics give users more flexibility in analyzing data. For details, see the comparison chart on pages 5-8. Enhancements to other SPSS Statistics modules Three new regularization methods have been added to SPSS Categories : Ridge Regression, the Lasso, and the Elastic Net. Regularization aims at improving predictive accuracy by stabilizing the parameter estimates and facilitates the analysis of high-volume data. SPSS Categories also offers three new predictive accuracy assessment methods: systematic multiple starts,.632(+) bootstrap, and cross validation (CV). The first method enables you to find a model that is optimal for describing the relations between variables; the other methods enable you to find those that are optimal for prediction. Together, these methods make it possible to create reliable predictive models from shallower-wider datasets. Improved research and reporting can also be achieved, using Amos 17.0, a product for structural equation modeling (SEM) that integrates with SPSS Statistics Enhancements to Amos 17.0 include the ability to write a Visual Basic program based on a model specified using Amos Graphics; to copy and paste part of one path diagram to another; and to automatically set up parameter constraints when creating a latent growth curve model. More details on Amos 17.0 can be found at com/amos. New functionality for generalists and for specialists In this release, there are features that make SPSS Statistics more accessible to beginners and generalists, and other capabilities that meet the needs of expert analysts and statistical programmers. RFM analysis With this release, SPSS Inc. introduces the SPSS EZ RFM module, which enables marketers to target campaigns more effectively by making the complexities of RFM analysis simple and straightforward. A custom interface guides marketers step by step, as they review the recency, frequency, and monetary value of customer transactions. Now even those without a strong statistical background can quickly gain clearer insight that will lead to more targeted, cost-effective and successful campaigns. And since marketers can perform this RFM analysis on their own, they can do so more frequently and consistently. (For more details on this new module, see SPSS Advanced Statistics was formerly called SPSS Advanced Models. 2

3 Additional visualization options If you need to create customized graphs of your results, or want to save special graph types as templates for others to use, the Graphboard feature of SPSS Statistics 17.0 offers integration with a new product, SPSS Viz Designer. With this new functionality a user can apply chart templates created in SPSS Viz Designer to analyses run in SPSS Statistics. (For additional information, please go to Statistical programmers will find additional graphing options available in SPSS Statistics This release extends support of the SPSS Statistics plug-in for R to include graphic packages written in that programming language. Since these can be saved as templates, analysts will be able to choose from an almost unlimited array of potential graph types when communicating their findings. Enhanced programmability SPSS has updated the plug-ins for Python, the.net version of Visual Basic, and R for compatibility with SPSS Statistics The R plug-in for SPSS Statistics 17.0 also includes the ability to drive chart creation from R and have the results included in the SPSS Statistics Output Viewer for report creation. More information about the SPSS Statistics Programmability Extension, free plug-ins created by SPSS Inc., custom procedures created by other users, and the SDK can be accessed at More support at the enterprise level Because organizations are increasingly relying on predictive analytics to drive business decision making, SPSS Inc. has enhanced several key features in SPSS Statistics 17.0 that provide easier enterprise integration, as well as the deployment and management of analytical assets. Improved Syntax Editor Expert users of the SPSS Statistics suite will welcome new features in the SPSS Statistics Syntax Editor such as autocompletion, color coding of syntax, a gutter to display line numbers and break point, and more. These help you create SPSS Statistics syntax more quickly and easily and check for errors before the task is executed. By catching errors early, these enhancements will make both analysis and report delivery more efficient. Deeper integration with SPSS Predictive Enterprise Services SPSS Predictive Enterprise Services is a platform that supports organizations in the management of analytical assets, automation of analytical processes, and efficient delivery of results as they move toward becoming Predictive Enterprises. The deeper integration available in SPSS Statistics 17.0 streamlines the use of SPSS technologies throughout the enterprise. Custom Dialog Builder SPSS Statistics 17.0 introduces a Custom Dialog Builder so that more experienced users can make existing dialogs easier for business users, and create dialogs for custom features built through programmability. The Custom Dialog Builder enables your organization s less experienced users to quickly learn how to perform routine operations efficiently, and gives programmers a way to deploy their work efficiently. For example, if your organization uses products from more than one SPSS product family SPSS Statistics and Clementine, for example you can define a common data access interface once, and then use it in both analytical tools to ensure consistent results. The SmartViewer product is replaced in this release by the new SPSS SmartReader user interface. This provides much the same functionality. For instance, report consumers will be able to view and pivot SPSS Statistics output and retrieve files from SPSS Predictive Enterprise Services. 3

4 Enhanced administrative tools New administrative tools available in SPSS Statistics Server provide IT staff with greater control in configuring, monitoring, prioritizing, troubleshooting, and optimizing their SPSS Statistics client/server environment. Information now available includes activity by SPSS Statistics users, and resources used in the execution of SPSS Statistics analysis. Also, someone opening a data file that is already in use would be automatically alerted to this, enabling teams to work together more efficiently and effectively by knowing who is accessing data at any given time. SPSS Statistics Server is officially supported for deployment in virtualization environments, giving organizations greater control over the resources it has access to, and greater flexibility in their chosen client/server configurations.
