How do you compare two sets of data in SAS?
Here’s how to check if two datasets in SAS are the same:
- Start the comparison procedure with the PROC COMPARE statement.
- Use the BASE=-option to specify the name of the first dataset.
- Use the COMPARE=-option to specify the name of the second dataset.
- Finish and execute the procedure with the RUN statement.
How do I compare two SAS codes?
How to compare SAS programs in SAS Enterprise Guide
- Install a file comparison tool. I like WinMerge.
- Set your File Comparison options in SAS Enterprise Guide. Select Tools->Options, then the File Comparison tab.
- Select the two files that you want to compare.
What is Proc compare in SAS?
The COMPARE procedure compares the contents of two SAS data sets, selected variables in different data sets, or variables within the same data set. PROC COMPARE compares two data sets: the base data set and the comparison data set. The procedure determines matching variables and matching observations.
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….Other Statistical Options.
| Statistical Option | Description |
|---|---|
| RANGE | Range |
| USS | Uncorr. sum of squares |
| CSS | Corr. sum of squares |
| STDERR | Standard Error |
What is the difference between PROC FREQ and PROC means?
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.
How to use proc compare with no options in SAS?
When you run a standard PROC COMPARE with no options, SAS will just compare observation 1 from the BASE dataset with observation 1 from the COMPARE dataset followed by comparing observation 2 from the BASE dataset compared with observation 2 from the COMPARE dataset and so on.
When to print 0 in Proc compare statement?
PROC COMPARE prints 0 for any summary statistic that is less than number. A report that contains many trivial differences is easier to read in this form. lists all variables and observations that are found in only one data set. using LISTALL is equivalent to using the following four options: LISTBASEOBS, LISTCOMPOBS, LISTBASEVAR, and LISTCOMPVAR.
What happens when you omit allobs in Proc compare?
If you omit ALLOBS, then PROC COMPARE prints values only for observations that are judged unequal. When used with the TRANSPOSE option, ALLOBS invokes the ALLVARS option and displays the values for all matching observations and variables. prints a table of summary statistics for all pairs of matching variables.
How does Proc compare with ID variable work?
By running a PROC COMPARE with ID variable, you can compare those records with a matching ID without having to explicitly merge your data together or create a new dataset. Using the same CLASS and CLASSFIT datasets from the SASHELP library, you may have noticed both datasets contain a NAME variable.
