SAS Help

In addition to help you can get from your coworkers, there is a vast amount of SAS programming support available to you. The following resources are available to help you enhance your SAS skills and to help solve your SAS problems.

Notice how the XML engine is indicated in PROC CONTENTS and that the number of observations is set to missing. For further guidance refer to SAS Help and Documentation, where the XML LIBNAME engine is documented extensively. 

It is worth taking special note of the MODE=INCLUDE option in the SYMBOL1 statement in Program 6.4. As stated in SAS Help and Documentation ... 

It is helpful to consider qualitatively the numerical magnitude of the surface tensional stabilization of a particle at a liquid-liquid interface. For simplicity, we will assume 6 = 90°, or that 7sa = 7SB- Also, with respect to the interfacial areas, J sA = SB, since the particle will lie so as to be bisected by the plane of the liquid-liquid interface, and. AB = rcr - The free energy to displace the particle from its stable position will then be just trr 7AB- For a particle of l-mm radius, this would amount to about 1 erg, for Tab = 40 ergs/cm. This corresponds roughly to a restoring force of 10 dyn, since this work must be expended in moving the particle out of the interface, and this amounts to a displacement equal to the radius of the particle. 

It is also convenient to compare the behavior of different dispersed catalysts with the help of the two following quantities the mass activity, MA, in Ag", and the specific activity, SA, in pA The values ofMA... 

The SAS SELECT statement is great for conditional processing because it has a mandatory OTHERWISE clause built into it to help catch unforeseen conditions. In a SAS SELECT statement, the code above would look like the code in the following program. 

Beginning with SAS 8, there are tools in SAS to help you read and write XML files. Starting with SAS 9.1, SAS provides XML import support via the XML LIBNAME engine (previously called SXLE) and the SAS XML mapper (previously called Atlas). 

I recommend that you follow a more traditional systems development life-cycle model (SDLC) when developing a comprehensive SAS macro-based reporting system. Unlike much of the one-time-only SAS programming that occurs for a clinical trial, you need to ensure that a general-purpose SAS macro system is robust enough to handle any problem it encounters. The systems development life-cycle approach to software development will help you to build strong software applications with SAS. 

Common clinical trial graphics are the focus of this chapter. First, we discuss the types of graphs that are most often encountered in clinical trial analysis and reporting. Then we examine the various tools that SAS provides to help produce these graphs. Sample graph programs are provided to show how many of these graphs can be produced. 

There are a number of SAS procedures that help to build the graphics most common to clinical trial reporting. The following table describes which SAS procedures make which graphs. 

The following resources will help you to write regulatory-compliant SAS applications. 

Take your problem to your company s SAS support personnel and resident SAS experts to see if they can help you. 

Hardcopy SAS manuals (user s guides and reference) and electronic documentation have evolved over the years. In SAS 6 and earlier versions, SAS manuals were available only in hardcopy, and you had to use the SAS windowing environment for electronic help. With SAS 8, you can still get hardcopy manuals and you can use the SAS windowing environment to access help just as before. However, SAS also sells a CD-ROM called SAS OnlineDoc for SAS 8 that gives you the SAS manuals in HTML or PDF format. Finally, you can now get free SAS 8 documentation over the Internet in HTML format from SAS at http //support.sas.com/documentation/onlinedoc/index.html. 

The community Web pages at SAS go into further detail on the use and development of SAS software. These Web pages are constantly updated with helpful details on how to make SAS work for you and on future developments of SAS software. I have found the Base SAS community page to be especially useful. You can find the SAS community pages at http //support.sas.com/rnd/intro.html. 

SAS Publishing provides a complete selection of books and electronic products to help customers use SAS software to its fullest potential. For more information about our e-books, e-learning products, CDs, and hardcopy books, visit the SAS Publishing Web site at support.sas.com/pubs or call 1-800-727-3228.

This is part of an ongoing PhD thesis by the first author. Funding is from Poderosa SA mining company (Peru) and NSERC grant to D. Gaboury. P. Bedard, R. Cox and D. Savard helped with the apparatus and data reduction. 

Several reports also suggest that adjunctive risperidone (Giakas, 1995 Jacobsen, 1995 Lombroso et al., 1995 McDougle et al., 1995 Ravizza et al., 1996 Stein et al., 1997)or olanzapine (Peris and Szerman, 2000) may be helpful in treatment-resistant OCD. Systematic data in pediatric samples are needed, however, before such an approach can be recommended, and there are anecdotal reports of increased obsessions and anxiety with the atypical neuroleptics (Alzaid and Jones, 1997 Andrade, 1998 Mottard and de la Sa-blonniere, 1999). 

Weissman and Paykel (1974) revised a previously developed questionnaire to assess the performance of individuals in different roles, called the social adjustment scale (SAS-R). These roles included (1) work, (2) housework, (3) parental role, (4) social leisure activities, (5) extended family relationships, (6) marital relationship, and (7) family unit. Functioning in the last four roles is an important indicator of interpersonal functioning. Having deep relationships outside the immediate family helps an individual to draw more social support. Furthermore, the success of relationships outside the family indicates that the person possesses competent social skills and is able to form and maintain meaningful relationships with others. Marital and familial relationships were the resources most easily accessible to the individuals. However, broken marital and familial relationships might generate stress and lead to the development of depression (Weissman, 1997). 

A similar success rate, four and 44 out of 50 attempts for the anatase and rutile polymorphs, respectively, was more recently found by Reinaudi et al. [68]. Their initial work differs from that of Freeman and coworkers in that the lattice energy (Eq. 2 with identical potential parameters) rather than the r12 cost function was used as the measure of quality during the SA stage. Although a better measure of quality for candidate structures that are similar to the desired structure, this definition of the cost function can be problematic, however, if there are very short interatomic distances. Thus, the benefit of using the r12 cost function, to help prevent creating candidate structures that may contain collapsed regions, is lost.
