I have 5 columns of data in an excelExcel spreadsheet.
Each row has either a 1 or a 0 (on or off) within each column.
I'm trying to determine the most common grouping or clustering of columns that have a 1. For example, it could be columns B&B & D are the most common grouping that have '1s'1s, followed by columns A,D D & E, etc.
What is this method of analysis called and how do I do it in Excel?
