Dear friends,I need to add a new attribute that should have two distinct values "open" and "closed" depending on two conditionals. First the value of another nominal attribute will be analyzed. Second it must obey a percentage established for "closed". Example: If the attribute has the value "industry" and the total of examples is not greater than 86% the value will be "closed" else "open". How can I implement these conditions in Rapidminer? I analyzed the "Generate Attributes" operator but I do not think it's the way.
