What does class mean in SAS?
The BY statement and the CLASS statement in SAS both enable you to specify one or more categorical variables whose levels define subgroups of the data.
(For simplicity, we consider only a single categorical variable.).
What does Proc mean?
programmed random occurrenceProc is an acronym for a programmed random occurrence that refers to a weapon, item or ability activating with the “Chance on Hit” or “Chance on Use” effect (an ability or a spell).
How do you define a proc in SAS?
PROC MEANS is one of the most common SAS procedure used for analyzing data. It is mainly used to calculate descriptive statistics such as mean, median, count, sum etc….Common Statistical Options.Statistical OptionDescriptionNMISSNumber of missing observationsMEANArithmetic averageSTDStandard DeviationMINMinimum12 more rows
What is Maxdec in SAS?
ID Statement. MAXDEC=number. specifies the maximum number of decimal places to display the statistics in the output.
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.
What does N mean in SAS?
As per SAS Documentation : “Definition of SAS Name Literals : A SAS name literal is a name token that is expressed as a string within quotation marks, followed by the upper- or lowercase letter n. … Name literals enable you to use characters (including blanks and national characters) that are not otherwise allowed.”
What does nway missing mean in SAS?
Herein, 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 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. Proc MEANS by default produces printed output in the LISTING window or other open destination whereas Proc SUMMARY does not.
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.
How do I convert character to numeric in SAS?
To convert character values to numeric values, use the INPUT function. new_variable = input(original_variable, informat.); The informat tells SAS how to interpret the data in the original character variable.
How do you transpose 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 .
How do I sort variables in SAS?
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.
How do you find the mean in SAS?
The arithmetic mean is the value obtained by summing value of numeric variables and then dividing the sum with the number of variables. It is also called Average. In SAS arithmetic mean is calculated using PROC MEANS.
How do you compare means in SAS?
To compare the means of two groups in SAS, you can use either the TTEST procedure or the ANOVA procedure. The null hypothesis is that there is no difference in mean between the two groups.
