Newb getting a strange "The example set contains non-nominal attribute sum(...."
Learner III
I've just used the template for Market Basket analysis (ie File -> Open Template -> Market Basket) on version 5.1.011
I have approx 100k rows to import.
I've imported my data as customerId (nominal) (this is a alphanumeric code) , itemId (nominal) (a numeric code based on UPC / EAN) and itemCount (integer) although I have "fudged" the itemCount column and set it always to 1.
However, when I get to the FP-Growth stage I see the error :"The example set contains non-nominal attribute sum(itemCount)_1239332 which is not allowed for FP Growth"
But... my itemCount is always an integer - in fact it's always 1... What am I doing wrong here ?
Thanks,
Richard.
