Explaining the Process of Merging Datasets in SAS

When merging datasets in SAS, you can use the MERGE statement to combine two or more datasets based on a common variable. This process allows you to consolidate information from multiple datasets into a single dataset.

To separate matches and non-matches into different output datasets, you can use the options available in the MERGE statement. By default, the MERGE statement creates an output dataset that contains all the observations from the input datasets, whether they match or not.

To create separate output datasets for matches and non-matches, you can use the IN= option in the MERGE statement. This option creates indicator variables that indicate whether an observation comes from a specific dataset. You can then use these indicator variables to filter the observations and create separate output datasets.

Overall, merging datasets in SAS allows you to combine and analyze data from multiple sources efficiently, while also offering flexibility in how you handle matches and non-matches in the output datasets.
