Proc means var statement. Variables in a BY statement are called BY variables.
Proc means var statement. You can do the same for your own data as well. PROC MEANS uses six combinations of two categorical variables to compute the number of observations, the mean, and the range. Aug 19, 2025 · specifies a numeric variable whose values weight the values of the variables that are specified in the VAR statement. cars; Class Make; Var MSRP Invoice; Run; By specifying the variable MAKE as the classification variable, there will be a separate analysis completed for each car maker. Tip: You can The core function of PROC MEANS is to analyze the values of variables that are defined as numeric variables. A procedure is invoked in a “PROC step” which starts with the keyword PROC, such as: PROC MEANS DATA=CLASS; VAR HEIGHT WEIGHT; The VAR or VARIABLES statement can be used with all procedures to indicate which variables are to be analyzed. com Apr 25, 2023 · The PROC MEANS procedure summarises data in descriptive statistics for variables across all the observations as well as within the groups of observations. See full list on listendata. PROC SQL will let you compute counts by a grouped variable, and then output a dataset with the same number of records as the input dataset with the count column added ("remerged summary statistic"). The weight variable does not change how the procedure determines the range, extreme values, or number of missing values. sas. If the value of the weight variable is To exclude observations that contain negative and zero weights from the analysis, use EXCLNPWGT. Restriction: If you omit variable and name (s) then PROC MEANS allows the statistic-keyword only once in a single OUTPUT statement, unless you also use the AUTONAME option. 6 days ago · WEIGHT Statement Specifies weights for analysis variables in the statistical calculations. Default: If you omit the VAR statement, PROC MEANS analyzes all numeric variables that are not listed in the other statements. If you omit the NOTSORTED option in the BY statement, then the observations in the data set either must be sorted by all the variables that you specify or must be indexed appropriately. Specifying the MISSING option in the CLASS statement enables you to control the acceptance of missing values for individual class variables. Note that most SAS/STAT procedures, such as PROC GLM, exclude negative and zero weights by default. Something like: proc means data=name; class class1; var var1; class class2; var var2; class class3; var var3; run; I don't want to writ Sep 15, 2015 · you can use more var variables in proc means by just mentioning the numeric variable names in the var statement separated by space. The following table describes how PROC MEANS treats various values of the WEIGHT variable. The PROC MEANS statement is the only required statement for the MEANS procedure. If you specify the MISSING option in the PROC statement, then the procedure considers missing values as valid levels for the combination of class variables. A where statment applies to the whole dataset. It is a powerful SAS procedure for summarizing or aggregating data. The first variable, School, has two values and the other variable, Year, has three values. If you want more variables in the output dataset you could list them on the class statement. 6 days ago · Results Examples References PROC MEANS Statement Computes descriptive statistics for variables. heart dataset. When I use the code below with one variable the code works fine. Try the code something like below proc means data=have mean std min max; var var1 var2 Use the TYPES statement and the WAYS statement to control which class variables that PROC MEANS uses to group the data. Are either of these close to what you want: proc means Dec 15, 2019 · In PROC MEANS, the automatic _TYPE_ variable is created in the output dataset when you use the CLASS statement. Specifying the MISSING option in the CLASS statement allows you to control the acceptance of missing values for individual class variables. The values of the variable do not have to be integers. Each proc has its own set of additional statements that are valid for that proc. SAS Procedures exist to carry out all the forms of statistical analysis. If you specify the following statements, PROC MEANS produces five basic stats (N, Min, Max, Mean, SD) for each numeric variable in the last created dataset. Use the CLASS statement to separate the analysis for different categories of your data. Identifies the analysis variables and their order in the output. proc means data = have; var var1; weight n; title "With weight"; run; proc means data = have; var var1; freq n; title "With Freq"; run; proc means data = have; var var1; Title "With neither Freq nor weight"; run;title; Learn how to use PROC SUMMARY in SAS, along with examples. When all variables are character variables, PROC MEANS produces a simple count of observations. You can compute statistics like calculating mean, standard deviation, minimum and maximum values, and many more statistical calculations. Do you have any additional comments or suggestions regarding SAS documentation in general that will help us better serve you? documentation. Are either of these close to what you want: proc means variable specifies the variable that the procedure uses to form BY groups. Sep 26, 2025 · If you specify the MISSING option in the PROC statement, then the procedure considers missing values as valid levels for the combination of class variables. For example, PROC MEANS does the following: calculates descriptive statistics estimates quantiles Identifies the analysis variables and their order in the output. Jul 23, 2015 · PROC MEANS is summarizing by class variables. Tip: To reduce the number of class variable levels, use a FORMAT statement to combine variable values. WEIGHT variable; Required Arguments variable specifies a numeric variable whose values weight the values of the analysis variables. The variable does not have to be an integer. When a format combines several internal values into one formatted value, PROC MEANS outputs the lowest internal value. Tip: You can The PROC MEANS statement is the only required statement for the MEANS procedure. And in the output out statement , use the autoname option so that the descriptic statistics produced will represent the respective statistics concatenated with variable names. Variables in a BY statement are called BY variables. Apr 27, 2015 · Is it possible to get the means of var1 grouped by class1, means of var2 grouped by class2, and means of var3 grouped by class3 in a single PROC MEANS statement. For multiway combinations of the class variables, PROC MEANS determines the order of a class variable combination from the individual class variable frequencies. If this statement is omitted, the default is to include all variables of the These examples have shown that you can have additional statements with a proc (for example, the var and class statements). You can use a WEIGHT statement and a FREQ statement in the same step of any procedure that supports both statements. You can specify more than one variable. proc means data = heart (where=(weight GE 140)) noprint; var Oct 8, 2016 · Missing values aren't included in proc means calculations by default. Note: If you specify fewer new variable names than the combination of analysis variables and identification variables, then the remaining output variables use the corresponding names of the ID variables as soon as PROC MEANS exhausts the list of new variable names. The _TYPE_ variable provides information about the level of classification for each observation in the output dataset. I am using the sashelp. Its analyses can be portrayed in the SAS Output Window (the default), or, with some additional statements within the PROC MEANS 'unit of work,' stored in SAS data sets. You can't have it selectively apply to some variables and not orhers.
