How to create dummy variable intervals, such as for times?
I am trying to use the nominal to numerical operator to create dummy variables. One of the attributes I want to convert is time (e.g. 12:30), but there are over 600 different times in the attribute data. I would like to assign each time data to an hour interval. Such as, all times from 7:00-7:59 would convert to a single dummy variable. Is there a way to have RapidMiner do this? Thank you for your help.
