Introducing the SAS Code Analyzer 2008-03-13 SAS Institute

This paper introduces the PROC SCAPROC procedure, the SAS Code Analyzer that is new in Release 9.2 of Base SAS Software. The paper examines the advantages of using the procedure, its syntax and phases of execution, and the output that the procedure can produce. If one is responsible for maintaining a large legacy SAS application, one is probably interested in finding ways to improve the performance of the application. This is especially true if the application makes many passes through the same data sets, and one knows that those passes could potentially be run in parallel. However, it can be difficult and tedious to convert an application to run parallel steps, even when one has a good understanding of the application.

Try, Try Again: Replication-Based Variance Estimation Methods for Survey Data Analysis in SAS 9.2 2008-03-13 SAS Institute

Complex survey samples are constructed with selection schemes that affect the usual random assumptions, so SAS/STAT software provides specialized procedures to analyze them: SURVEYMEANS, SURVEYFREQ, SURVEYREG, and SURVEYLOGISTIC for means, frequencies, regression, and logistic analysis, respectively. These procedures all use the Taylor series expansion method for variance estimation, which is usually considered to be the "Gold standard" when it is practical to compute. However, replication methods are also widely used in practice for variance estimation. Replication methods, such as the jackknife and Balanced Repeated Replication (BRR), replace complex algebra with simple repeated analysis. They enable the user to analyze the data without the original sample design, protecting survey security, and they ease the task of estimating variances for nonlinear quantities.

Updates to SAS Power and Sample Size Software in SAS/STAT 9.2 2008-03-13 SAS Institute

Procedures for power analysis and sample size determination were introduced in SAS/STAT 9.1 along with a Web application for performing these analyses. SAS/STAT 9.2 adds analyses for several new designs, enhances some existing analyses, and replaces the Web application with a desktop application for your PC. The new analyses include logistic regression; confidence intervals, equivalence tests, and noninferiority tests for a binomial proportion; and the Wilcoxon Mann-Whitney test for two distributions. These new analyses join the ones already available with SAS/STAT 9.1: general linear univariate models, one-way ANOVA, multiple regression, t tests, confidence intervals and equivalence tests of means, tests of proportions, and survival rank tests.

SAS Stat Studio: A Programming Environment for High-End Data Analysts 2008-03-13 SAS Institute

SAS Stat Studio 3.1 is new statistical software in SAS 9.2 that is designed to meet the needs of high-end data analysts - innovative problem solvers who are familiar with SAS/STAT and SAS/IML but need more versatility to try out new methods. Stat Studio provides a rich programming language, called IMLPlus, that blends an Interactive Matrix Language (IML) with the ability to call SAS procedures as functions and to create customized dynamic graphics. For standard tasks, Stat Studio provides the same interactive graphics and statistical capabilities available in SAS/INSIGHT, and so it serves as a programmable successor to SAS/INSIGHT.

Getting Started With ODS Statistical Graphics in SAS 9.2 2008-03-13 SAS Institute

ODS Statistical Graphics (or ODS Graphics for short) is major new functionality for creating statistical graphics that is available in a number of SAS software products, including SAS/STAT, SAS/ETS, SAS/QC, and SAS/GRAPH. With the production release of ODS Graphics in SAS 9.2, over sixty statistical procedures have been modified to use this functionality, and they now produce graphs as automatically as they produce tables. In addition, new procedures in SAS/GRAPH use this functionality to produce plots for exploratory data analysis and for customized statistical displays. SAS/GRAPH is required for ODS Graphics functionality in SAS 9.2. This paper presents the essential information one needs to get started with ODS Graphics in SAS 9.2.

What's New in the 4.2 Releases of SAS Enterprise Guide and the SAS Add-In for Microsoft Office 2008-03-13 SAS Institute

SAS Enterprise Guide, the SAS Add-In for Microsoft Office for SAS 9.2, and SAS Enterprise BI Server 4.2 provide many new enhancements to help SAS programmers, business analysts, and other business users become more productive with SAS. This presentation will introduce the user to some of the highlights, including a revamped User Interface (UI) in SAS Enterprise Guide, the ability to open SAS Reports from the SAS Add-In, a new PROC REPORT-based wizard, and much more. This paper gives a broad overview of the products and enhancements and point one to some of the other SAS Global Forum presentations that cover some of the specific enhancements in greater depth. One will find many reasons to upgrade to the new releases or to become a new SAS user.

What's New in SAS/ACCESS 2008-03-13 SAS Institute

The group of SAS/ACCESS products contains many enhancements, features and new products. The ACCESS R&D group also supports sister technologies, which include Metadata utilities and SQL textualization. It is beyond the scope of this paper to detail all of the modifications made in the SAS/ACCESS engines for SAS 9.2; however, documentation resources and highlights should help one discover how one can take advantage of the SAS 9.2 SAS/ACCESS enhancements.

Deployment for SAS 9.2 and Beyond 2008-03-13 SAS Institute

As the SAS architecture has grown to serve the complex and distributed challenges of enterprise-wide deployments, the tools used to plan, deliver, install, and configure SAS software have needed to grow in lockstep. The 9.2 release of the SAS Enterprise Intelligence Platform delivers an accompanying revolution in the way SAS software is deployed. The paper will summarize advancements such as electronic software download, customized orders, silent installations, streamlined dialog boxes, deployment capture/replay, and SAS Software Depot management. Looking further into the future, SAS Deployment R&D already has several innovative efforts underway. The paper will close by describing initiatives in the areas of open source standards and tools, update services, and Information Technology Infrastructure Library (ITIL) framework adoption.

Creating Complex Reports 2008-03-13 SAS Institute

This paper is for intermediate SAS programmers who want to see a gallery of complex reports and review the code that produced them. It covers the pros and cons of PROC REPORT, PROC TABULATE, and DATA _NULL_ for each report. All report output is produced using ODS (rather than LISTING) output. Get out the wrenches and tool belts and fasten one's seat belt for the ride, this is going to be a real nuts and bolts paper presentation.

Going Beyond Simple Information Maps to Improve Access to Data Sources 2008-03-13 SAS Institute

SAS Information Maps provide users with easy access to rather simply-defined data sources. Although they can be directed to external relational databases, performance can be an issue due to the way in which queries are built and passed via the LIBNAME engine within the SAS/Access products. In addition, sometimes it is necessary to perform nested queries to databases in order to provide more meaningful information in reports. This paper will explore options to assure performance and go beyond simple table joins to provide easier access to end users.
