Proc Compare Sas Example. For both types of output data sets, proc compare assigns one of the following data set labels: If you omit compare=, the comparison data set is the same as the base data set, and proc compare compares variables within the data set.
For example, in the following proc compare step, the novalues option suppresses the part of the output that shows the differences in the values of matching variables: Comparing variables in different data sets; This is how the steps above look.
Proc compare checks each variable in one data set to determine whether it matches a variable in the other data set. This example shows the most complete report that proc compare produces as procedure output. The nature of the comparison depends on whether all by variables are in the comparison data set and, if they are, whether their attributes match the ones of the by variables in the base data set.
After running proc compare has completed i obtain information much like the below example. To use a by statement with proc compare, you must sort both the base and comparison data sets by the by variables. Matching variables are variables with the.
Here’s how to check if two datasets in sas are the same: By processing with proc compare. The most basic default usage of proc compare is to simply specify one dataset as your “base” dataset using the base argument and then specify the dataset you would like to compare it against using the compare argument:
Proc summary with one variable. Data set attributes (set by the data set options type= and label=). The compare procedure compares the contents of two sas data sets, selected variables in different data sets, or variables within the same data set.
This example shows the most complete report that proc compare produces as procedure output. Use the power of proc compare to not only compare variable attributes, but also the accuracy of data values. Proc compare base=proclib.one compare=proclib.two novalues;
