Foundation SAS Enhancements in SAS® 9.2

The following provides an overview of the enhancements that have been made to products in Foundation SAS for SAS 9.2.

Base SAS
ODS Statistical Graphics

Enhancements to Base SAS®

Base SAS 9.2 includes the following enhancements:

ODS Statistical Graphics

ODS Statistical Graphics, experimental in SAS 9.1, is in production in SAS 9.2. Over 60 statistical procedures in SAS/STAT, SAS/ETS, SAS/QC, and Base SAS have been modified to use ODS Graphics functionality. The procedures now produce graphs as automatically as they produce tables. In addition, three new SAS/GRAPH procedures (SGPLOT, SGPANEL, and SGSCATTER) use this functionality to produce plots for exploratory data analysis and for customized statistical displays. We've extended the functionality of ODS Graphics with: For an overview of the new functionality, see Getting Started with ODS Statistical Graphics in SAS 9.2.

SAS/ACCESS® Software

A new in-database feature in SAS/ACCESS 9.2 Interface to Teradata substantially improves performance by moving analytic tasks closer to your data. You can publish custom formats, as well as most formats that SAS provides, so that they run inside the Teradata Enterprise Data Warehouse (EDW). A SAS_PUT() function, which emulates the traditional SAS PUT function and supports the use of SAS formats inside the database, is created and registered for use in SQL queries.

Other new features include new or enhanced functions for the SQL_FUNCTIONS= LIBNAME option, a new SQL_FUNCTIONS_COPY= LIBNAME option for specific DBMSs, and new or enhanced hyperbolic, trigonometric, and dynamic SQL dictionary functions.

For most DBMSs, you can now create temporary tables using DBMS-specific syntax with the new DBMSTEMP= LIBNAME option. For HP Neoview, you can use the new BULKEXTRACT= LIBNAME option along with new data set options for bulk loading and extracting. In addition, SAS/ACCESS software supports additional operating environments for existing DBMSs.

SAS/ETS® Software

The PANEL procedure expands the estimation capability of the TSCSREG procedure in the time-series cross-sectional framework. The new methods include between estimators, pooled estimators, and dynamic panel estimators using the GMM method. The COUNTREG procedure implements count data models such as Poisson regression, negative binomial regression with linear and quadratic variance functions, zero-inflated Poisson (ZIP) model, and the zero-inflated negative binomial (ZINB) model. The new SIMILARITY (experimental) procedure provides similarity analysis of time series data.

The new ESM procedure provides forecasting using exponential smoothing models with optimized smoothing weights. In addition, the SASEHAVR interface engine is now in production and available to Windows users for accessing economic and financial data residing in a HAVER ANALYTICS Data Link Express (DLX) database.

SAS/GeneticsTM Software

SAS/Genetics software includes two new experimental procedures, the BTL procedure and the GENESELECT procedure. Several enhancements have been made to the ALLELE procedure. A format of genotype columns not previously supported can now be accommodated by the ALLELE, CASECONTROL, FAMILY, and HAPLOTYPE procedures.

SAS/GRAPH® Software

All SAS/GRAPH procedures now support ODS styles for all devices and include significant enhancements. The upgraded features include:

SAS/IML® Studio

SAS/IML Studio (formerly known as SAS Stat Studio) is software for data exploration and analysis. It provides a highly flexible programming environment in which you can run SAS/STAT or SAS/IML analyses and display the results with dynamically linked graphics and data tables. SAS/IML Studio is intended for data analysts who write SAS programs to solve statistical problems but need more versatility for data exploration and model building. The programming language in SAS/IML Studio, which is called IMLPlus, is an enhanced version of the IML programming language. IMLPlus extends IML to provide new language features, including the ability to create and manipulate statistical graphics, call SAS procedures as functions, and call computational programs written in C, C++, Java, and FORTRAN. This software also includes an interface to the R language. SAS/IML Studio runs on a PC in the Microsoft Windows operating environment and is distributed with SAS/IML software.

SAS/OR® Software

SAS/OR 9.2 software continues the mathematical optimization improvements delivered in previous releases. Several new and enhanced features, including a new suite of accelerated solvers for linear, mixed-integer, quadratic, and general nonlinear optimization, expand the scale and scope of problems that SAS/OR software can address. The new OPTMODEL procedure provides an algebraic language designed for building and solving optimization models, embedded within the SAS language. The new OPTLP, OPTMILP, and OPTQP procedures enable the direct solution of linear, mixed-integer, and quadratic optimization models represented in industry standard formats. SAS/OR 9.2 software also features the first production versions of the GA procedure (for optimization with genetic algorithms), the Earned Value Management macros (for evaluating and predicting performance in executing project schedules), and SAS Simulation Studio (for discrete event simulation of systems).

SAS/QC® Software

Creating consistent output is easier now that the ANOM, CAPABILITY, CUSUM, MACONTROL, PARETO, RELIABILITY, and SHEWHART procedures produce graphs that conform to ODS styles. Also, with ODS Graphics (experimental in SAS/QC 9.2), you can obtain the highest quality output with minimal syntax and full compatibility with graphics produced by SAS/STAT and SAS/ETS procedures.

The SAS ADX Interface for Design of Experiments includes enhancements related to response surface designs, mixture designs, general factorial designs, and split-plot designs. Furthermore, ADX can now import data from SAS data sets or external file formats, and it can export design information to SAS data sets or external file formats.

SAS/STAT® Software

SAS 9.2 brings several new procedures to SAS/STAT software, some of which were available as experimental Web downloads for SAS 9.1.3.
