What does nway missing mean in SAS?
If you omit the MISSING option, the SUMMARY procedure excludes any rows with a missing value in a CLASS variable from the resulting output SAS data set.
The NWAY options instructs the SUMMARY procedure to only create rows with a combination of all class variables..
What does Proc means do in SAS?
One of the most powerful and flexible Procedures you’ll find in the SAS System is PROC MEANS. You can use it to rapidly and efficiently analyze the values of numeric variables and place those analyses either in the Output Window or in a SAS Data Set (or both).
What does output Proc mean?
The output statement sends output to a dataset; you also can use ods output as you can with any proc. proc means data=sashelp. class; class sex; types sex; var height weight; output out=class_means mean= sum= /autoname; run; To use ods output you need to know the name of the table produced by the proc.
Does Proc means ignore missing values?
PROC MEANS excludes missing values for the analysis variables before calculating statistics. … If a FREQ variable value is missing or nonpositive, PROC MEANS excludes the observation from the analysis. If a WEIGHT variable value is missing, PROC MEANS excludes the observation from the analysis.
What does SAS mean?
Special Air ServiceSAS is often an abbreviation for “Special Air Service”, including: Special Air Service, a special forces unit of the British Army. Special Air Service Regiment, a special forces unit of the Australian Army. 5th Special Air Service, a Belgian Second World War formation.
Why is array used in SAS?
A SAS array is a convenient way of temporarily identifying a group of variables for processing within a data step. Once the array has been defined the programmer is now able to perform the same tasks for a series of related variables, the array elements.
How do you transpose data in SAS?
The general format of PROC TRANSPOSE is: PROC TRANSPOSE DATA=Dataset-name OUT=New-dataset-name; BY variable(s); COPY variable(s); ID variable; VAR variable(s); RUN; In the SAS code above: The PROC TRANSPOSE statement tells SAS to execute the transpose procedure on an existing dataset called Dataset-name .
What does Proc Summary do?
Proc Summary stores descriptive statistics in a data set. Proc Means displays descriptive statistics in output destinations. For example the HTML destination.
How do you plot a histogram in SAS?
The components of the SAS HISTOGRAM statement are:Variables. This is used to create SAS histograms. If you do not specify variables in a VAR statement or in the HISTOGRAM statement, then by default, a histogram is created for each numeric variable in the DATA= data set. … Options. It adds features to the histogram.
What is the difference between proc means and proc univariate?
PROC UNIVARIATE can calculate extreme observations – the five lowest and five highest values. Whereas, PROC MEANS can only calculate MAX value. … Whereas, PROC MEANS does not support normality tests.
How do you find percentiles in SAS?
For commonly used percentiles (such as the 5th, 25th, 50th, 75th, and 95th percentiles), you can use PROC MEANS and the STACKODSOUTPUT option, which was introduced in SAS 9.3, to create an output data set that contains percentiles for the multiple variables in a more convenient format.
What is Maxdec in SAS?
ID Statement. MAXDEC=number. specifies the maximum number of decimal places to display the statistics in the output.
