What are some of the applications of a HMM in the marketing field - specifically CRM and targeted marketing?
For example, is it mainly for predicting an outcome given a sequence? Such as if web site visitor visits {Page 2, Page 54, page 23} what is the probability they will $<next>$ visit page 22? Or visit page 22 in that session?
Is HMM a stand alone technique or normally coupled with other things?
