Rows (observations) Columns (variables) 7 Column Names Column names can be up to 32 characters long. It is recommended that column names also start with a letter or underscore include only letters, underscores, and numbers. 8 Enterprise Guide allows spaces and special symbols in variable names because it invokes the VALIDVARNAME=ANY option when SAS initializes. Not all SAS environments invoke this option. You should follow SAS standard naming conventions for column names if you anticipate running code generated by Enterprise Guide in other SAS applications. Standard naming rules are that columns must start with a letter or underscore, and that the remaining characters are letters, underscores, or numbers. A new option in Enterprise Guide 6.1 allows you to set variable naming rules. To force Enterprise Guide to follow standard SAS naming conventions, select Tools Options Data General and in the Naming Options pane, change Valid variable names to Basic variable names (V7).

ALL RIGHTS RESERVED. 2.1 Understanding SAS Data Structure 2-7 Column Type A column’s type is either character (string) or numeric. Character values are 1 to 32,767 characters long. Numeric values can be numbers currency date (days from 01JAN1960) time (seconds from midnight). 12 As well as name and type, another required column attribute is length. Length refers to the number of bytes that are used to store each of the variable's values in a SAS data set. Character values are stored with a length of 1 to 32,767 bytes. One byte equals one character. Numeric values are stored as floating point numbers in 8 bytes of storage by default. Eight bytes of floating point storage provide space for 16 or 17 significant digits. Formats A format is used to control how values are displayed. Formats do not affect how values are stored. Format: Width: Stored value: DATE 9 17227 Format: DOLLAR Width: 10 Decimal Places: 2 Stored value: 234.60 13 A format (display format) is an instruction that you apply to a column. The format tells Enterprise Guide how data values should be displayed. Use formats to control the appearance of data values or to group data values for analysis.

ALL RIGHTS RESERVED. 4.1 Filtering and Sorting Data 4-7 Business Scenario Preparing the new data set requires only filtering and sorting, so any of the query tools can be used. 13 The Filter tab builds an SQL WHERE clause that looks at every row of data and returns only those rows that satisfy the filter conditions. When you create more than one filter on your data, you can specify whether the relationship between the filters is AND or OR. AND returns rows of data only when all the expressions connected by an AND are true. OR returns data rows when at least one of the expressions connected by an OR is true. Whether you use AND or OR, if none of the expressions is true, no rows of data are returned. If you enter data values in the third field, remember that character values are case sensitive (for example, "CA" ≠ "Ca"). in the third field returns a maximum of 250 unique data values from the column in the first Clicking field. If you want Enterprise Guide to return the next 250 unique data values, select More Values. Each time you select More Values, the next set of distinct values for the variable is displayed in addition to the initial values. The number of values that are retrieved each time is specified by the number of distinct column values that you have for each request option that is found in Tools Options. Comparison operators that are available in the Edit Filter Condition dialog box include the standard comparison operators, as well as the following operators: IN (a list of values) Is equal to an item in the list. Example: category in ("BREAD","MEAT") BETWEEN Evaluates an inclusive range. Example: income between 60000 and 80000 IS MISSING Performs a test for missing values. CONTAINS Contains a string.

ALL RIGHTS RESERVED. 4.3 Grouping and Summarizing Data in a Query 4-31 Grouping Data The Select Data tab can be used to group and summarize data. Choose a statistic for columns to be summarized. Columns without an assigned statistic automatically define the groups. 48 A summarized column can also be created by using the New Computed Column Wizard. The order of the columns on the Select Data tab determines the initial grouping hierarchy. However, this can be modified in the Summary Groups pane. To modify the grouping structure of the data, clear the Automatically select groups check box and select Edit Groups. Statistics include the following: AVG, MEAN STD (standard deviation) COUNT, FREQ, N (number nonmissing values) STDERR (standard error of the mean) CSS (corrected sum of squares) SUM CV (coefficient of variation) SUMWGT (sum of WEIGHT variable values) MAX or MIN T (Student's t-value testing the hypothesis that the population mean is zero) NMISS (number of missing values) USS (uncorrected sum of squares) PRT (two-tailed p-value for Student's t statistic) VAR (variance) RANGE (range of values) Some summary functions enable you to select DISTINCT as part of the function. For example, the summary statistic AVG computes the average for all observations within each group. However, the summary function AVG DISTINCT excludes duplicate values in the calculation so that the computed statistic is the average of only the distinct values within each group.

ALL RIGHTS RESERVED. 4.3 Grouping and Summarizing Data in a Query 4-33 Filtering Data The Filter Data tab can be used to filter both raw data and summarized data. 52 First, the query extracts, from the table or tables, all rows that satisfy the conditions specified in the Filter the raw data pane. Then the resulting data is grouped by the assigned grouping variable, and summary statistics are computed for each unique group as defined on the Select Data tab. Further subsetting that is defined in the Filter the summarized data pane is then applied to the summarized values. Filtering grouped data is the same as using the HAVING clause in an SQL query.

For the salary distribution for both US and AU, there are a few extreme values at the high end and a concentration of values at the low end of the distribution, so the right tail of the distribution curve is longer (right-skewed). For such data, the skewness statistic is greater than zero. If the data is left-skewed, the skewness statistic is less than zero. d. Run the task and replace the results. Verify that the additional skewness statistic was added to the report. Save the Chapter5 project. Copyright © 2014, SAS Institute Inc., Cary, North Carolina, USA.

Creating and Applying a Custom Percentage Format You might want to display a percent sign (%) after the percentage values in your table created by the Summary Tables task. If you use the PERCENTw.d format, it multiplies data values by 100, and then adds a percent sign (%) to the end of the formatted value. The Summary Tables task already multiplied the values by 100 to compute the percent. Therefore, if you use the PERCENTw.d format to format the values, they are incorrect. Because you do not want the value multiplied by 100, you need to create a picture format. Use PROC FORMAT to add the percent sign to the value. a. Complete the Level 2 exercise. b. Open and run the e105e06 SAS program. This program creates a user-defined format named MYPCT that rounds values to the nearest tenth and adds a percent sign. c.

Yes No 23 Multiple Process Flows Creating multiple process flows provides another way to order and group similar tasks within a single project. 25 Using multiple process flows is a convenient way to group project items so that you can execute them as a group rather than individually. Using a process flow is particularly useful when the following conditions exist: • A specific order in which tasks and code should execute is present. For example, output from one task serves as input to another. • Changes to the underlying data and the tasks associated with a data source must be updated. • A desire to execute tasks outside of the SAS Enterprise Guide environment occurs. Copyright © 2014, SAS Institute Inc., Cary, North Carolina, USA. ALL RIGHTS RESERVED. 7-14 Chapter 7 Customizing and Organizing Project Results Autoexec Process Flow If there is a process flow named Autoexec, SAS Enterprise Guide prompts you to run the process flow each time that the project is opened. 26 Scheduling Updates Projects or individual process flows can be scheduled to update based on a certain time or event. 27 When you schedule an Enterprise Guide project via the Enterprise Guide scheduler, a Visual Basic script is created. This script is executed in accordance with the parameters that are supplied to the Windows Scheduler plug-in. If both the SAS server and the Enterprise Guide client reside on a single machine, scheduling a project is straightforward. However, if Enterprise Guide is configured to execute SAS processes on a remote server and the SAS server is configured to prompt for a user name and password, additional setup is required to enable the authentication process to complete. If logon credentials for the SAS Metadata Server cannot be saved on the local machine, scheduling of Enterprise Guide projects is not possible.

Using this process flow, you can quickly identify the different parts of the program and see how the parts are related. • Analyze for Grid Computing: When you analyze a program for grid computing, Enterprise Guide identifies the parts of the program that are not dependent on one another. These parts can run simultaneously on multiple computers. This means that Enterprise Guide returns the results faster. When SAS analyzes a program, lines of SAS/CONNECT code are added to your original program. Therefore, you must have a license for SAS Grid Manager or SAS/CONNECT to analyze a program for grid computing. Copyright © 2014, SAS Institute Inc., Cary, North Carolina, USA. ALL RIGHTS RESERVED. A.1 Writing and Submitting SAS Programs A-9 • Analyze for Internationalization: When you analyze a program for internationalization, Enterprise Guide identifies lines of code that might contain syntax that is specific to a particular geographic location. Examples include locale-specific currency and date formats or Unicode problems. When you analyze a program for internationalization, SAS Enterprise Guide lists the lines of code that might be affected and suggests substitutions when it is possible. All options run the code behind the scenes to complete the analysis. If a data set is open in the Enterprise Guide session, the analysis might fail. To view and close any open data sets, select Tools View Open Data Sets. Embedding Programs in a Project New SAS programs are embedded in the project so that it is saved as part of the .egp file.

Be aware of the following exceptions: Code that calls X commands or SYSTASK might not work unless this permission is granted by the administrator. Code that normally causes a window or prompt to appear in the SAS windowing environment (DEBUG, PROC FSLIST, AF applications) does not work in SAS Enterprise Guide. Code that terminates the SAS process with ABORT or ENDSAS calls terminates the connection between SAS Enterprise Guide and the SAS server. 29 For more information about enabling X and SYSTASK commands, go to http://blogs.sas.com/content/sasdummy/2009/11/19/using-the-x-and-systask-commands-from-sasenterprise-guide/.
