What is given in the output of Proc contents?
PROC CONTENTS produces three tables of output for a data set: attributes, engine/host information, and variables.
What are the default output of proc MEANS?
By default, PROC MEANS generates N, Mean, Standard Deviation, Minimum and Maximum statistics. The most frequent statistical options used in PROC MEANS are listed below against their description. Suppose you want to see only two statistics – number of non-missing values and number of missing values.
What is the use of nway in SAS?
The NWAY options instructs the SUMMARY procedure to only create rows with a combination of all class variables. These options are available only when used with the CLASS statement, not with the BY statement.
How do I run Proc contents?
The basic syntax of PROC CONTENTS is: PROC CONTENTS DATA=sample; RUN; As with all SAS procedures, the DATA command (which specifies the name of the dataset) is optional, but recommended. If you do not specify a dataset, SAS will use the most recently created dataset by default.
What does VAR mean in SAS?
identifies the analysis variables
The VAR statement identifies the analysis variables and their order in the output. If you omit the VAR statement, then PROC HPSUMMARY analyzes all numeric variables that are not listed in the other statements. When all variables are character variables, PROC SUMMARY produces a simple count of observations.
What is output statement?
The OUTPUT statement tells SAS to write the current observation to a SAS data set immediately, not at the end of the DATA step. If no data set name is specified in the OUTPUT statement, the observation is written to the data set or data sets that are listed in the DATA statement.
What is the use of nway In Proc means?
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 is the difference between Proc means and NOPRINT?
