|Type of Tool||SAS Macro|
|Description||This set of Macros creates side-by-side boxplots by grouping variables with similar ranges onto the same graph. This is a quick way to check the distribution of several variables. This procedure can also be used after calling the Deltas macro, to check the distribution of changes from baseline.|
|Classification Graph Type||Boxplot|
|Macro Parameters|| Dataset: Dataset to use|
Group: Optional grouping variable
Varlist: List of variables to Boxplot
Maxperplot: Maximum number of variables on a graph
Tolerance: Tolerance Pecentage(T)(0-100) (70 is a good start.)
If the range of B is within T% of A, then put on the same graph
Catalog: Graphics catalog to use
