hi. i`m working in a model to detect credit card transactions (tx) fraud. first i split the tx according the cardholder`s valid tx behavior. then i show the tx to some true/false tests with result 1 or 0. now a want to add all those tests values with a weight to determinate a score, and dont`know how to determinate them (the weights). i have different kinds of tx with a lot of variables and a final one (binay) for fraud or valid transaction
is there any free software or something to implemente on excel to determinate those weights. thanks . . ================================================================ This list will soon be replaced by the new list EDSTAT-L at Penn State.
