abandoned carts statistics?

hi all,

I am new to runing cs-cart and I have been watching my admin backend, especially the abandoned carts. it looks like there are a lot of carts which have been abandoned, so I was wondering if anyone else who has an online shop can give me some facts on abandoned carts VS carts which are checked out and payed for?

Is there a way to find out why a cart might have been abandoned? can I somehow get a trigger from the cs-cart php code when a user leaves the shop and abandons his or her cart? if I can get a trigger like this I might be able to get more statistics.
