How do you use proc transpose?
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 ..
How do you use proc sort?
If you list just one variable, then SAS will sort the observations in the dataset based on ascending values of that variable. … You can sort in descending order by placing the keyword DESCENDING before the variable name that you want the dataset to be sorted on. … You can sort by as many variables as are in the dataset.
What is proc transpose in SAS?
PROC TRANSPOSE is a powerful yet underutilized PROC in the Base SAS® toolset. … It contains three sample SAS® input files, a set of basic PROC TRANSPOSE variations, and their output results. There is a Summary Sheet at the end of the paper as well for later reference.
What is Proc Tabulate in SAS?
Proc tabulate is predominately used to make nice looking tables. Unlike proc freq this procedure can handle multiple variables in the row and column expressions. It can also handle multiple levels in both rows and columns whereas proc freq will only create two variable contingency tables.
What does nway missing mean in SAS?
Also know, 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 nway mean in SAS?
NWAY. specifies that the output data set contain only statistics for the observations with the highest _TYPE_ and _WAY_ values. When you specify class variables, this corresponds to the combination of all class variables. Interaction: If you specify a TYPES statement or a WAYS statements, PROC MEANS ignores this option …
What proc is appropriate for obtaining summaries about numeric variables?
The DATA= option in the PROC statement identifies the data set to be summarized and the VAR statement lists one or more numeric variables to be analyzed.
How do you use proc print?
The general format of PROC PRINT is: PROC PRINT DATA=dataset; BY variable(s); ID variable; VAR variable(s); RUN; In the SAS code above, PROC PRINT tells SAS to execute the print procedure on the dataset specified by the DATA command. As with all SAS procedures, the DATA command is optional, but recommended.
What does Proc Summary do in SAS?
When we specify NWAY, Proc Summary limits the output statistics to the observations with the highest _TYPE_ value. This means, that SAS outputs only the observations where all class variables (if any) contribute to the statistic.
What is Proc Freq?
The PROC FREQ is one of the most frequently used SAS procedures which helps to summarize categorical variable. It calculates count/frequency and cumulative frequency of categories of a categorical variable. … It also produces bar charts and tests for association between two categorical variables.
What does Proc sort do?
What Does the SORT Procedure Do? The SORT procedure orders SAS data set observations by the values of one or more character or numeric variables. The SORT procedure either replaces the original data set or creates a new data set. PROC SORT produces only an output data set.
How do I use PROC FREQ in SAS?
Syntax. PROC FREQ DATA=sample ORDER=freq; TABLE State Rank / MISSING; RUN; The ORDER=freq option in the first line of the syntax tells SAS to order the values in the table in descending order.
How do you use proc?

What is the difference between proc means and proc freq?
PROC MEANS is used to calculate summary statistics such as mean, count etc of numeric variables. It requires at least one numeric variable whereas Proc Freq does not have such limitation. In other words, if you have only one character variable to analyse, PROC FREQ is your friend and procedure to use.
What does it mean to transpose?
transitive verb. 1 : to change the relative place or normal order of : alter the sequence of transpose letters to change the spelling. 2 : to change in form or nature : transform. 3 : to render into another language, style, or manner of expression : translate.
How do I use proc compare in SAS?
proc sort data=compare; by DOB; run; proc compare base=demog (keep=unique weightkg) compare=compare (keep=unique weightkg); run; As in other SAS procedures and data step, it is possible to select observations and variables in the datasets that are going to be used.
What is _type_ in SAS?
The variables _FREQ_ and _TYPE_ are automatically added to the summary data set when the OUTPUT statement is used. _FREQ_ is the count of the number of observations available for use and _TYPE_ is a numeric flag which indicates the subgroup of the CLASS variables summarized by that observation in the output data set.
How do you output proc means to SAS dataset?
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.
What is Proc Summary?
Proc SUMMARY and Proc MEANS are essentially the same procedure. Both procedures compute descriptive statistics. The main difference concerns the default type of output they produce. … Inclusion of a VAR statement in both Proc MEANS and Proc SUMMARY, produces output that contains exactly the same default statistics.
