Sportsbetting

#1
Hi there,

Hoping someone could point me in the right direction on a case study for a Sportsbetting website. I have a sample list of customers along with the different sports and leagues they've placed a wager on. I also know whether those customers are positive revenue to the business or negative revenue. I'm trying to identify betting patterns among a group of negative revenue customers so that I can find others who fit the same criteria. Any suggestions where to start?

Thanks
Jay
