Merge Key Variables to Associate with Input SAS Data Set
Use this field to specify the variables from the {link}{Emphasis}Subset Data Set to Use for Normalization by which to merge data from the {link}{Emphasis}Input SAS Data Set.
The same variables must exist in the {link}{Emphasis}Input SAS Data Set. Only observations that have the same value(s) of the Merge Key Variables in both data sets are carried through in the analysis.
To Specify One or More Merge Key Variables:
| 8 | Specify the {link}{Emphasis}Subset Data Set to Use for Normalization. |
All of the variables in the specified subset data set are displayed in the Available Variables field.
| 8 | Examine the list of available variables. |
| 8 | Highlight one or more variables whose values are to be used for merging the data sets. |
