For me, the Experimenter as suggested by "Martin" is an excellent way.

Kind regards,

I believe the most reliable way to compare different classifiers in WEKA can be accomplished using WEKA "Experimenter".

Hi,
I'm quite new to weka and data mining and I have to develop a project.

My idea is to use data from ended auctions of Ebay (Category of the item, shipping cost, auction duration, condition of the item, user's feedbacks) to build a model to predict the probability of sale of a given item.
The dataset that I have built is composed by those attributes:
end_price (numeric)
shipping_cost (numeric)
item_condition (nominal)
item_category (nominal)
auction_duration (nominal)
user_feedback (numeric)
user_feedback% (numeric)
end_auction_day (nominal)
and the class attribute is the "item_sold" one, with two possible values: YES or NO.

For my purpose I was looking for a classifier that outputs the probability that an item will belong to class YES, so that if a user inputs "item_category,auction_duration,feedback,shipping,cost" he will then receive as an output the probability of selling his item.

I have tried with bayesian classifiers but I am not sure they are the right choice to this aim.
Any hint on the way I should take to find the right classifier? Is this kind of classification problem feasible?

Thank you very much!
Francesca
