11.5. From HTTP Logs to CVMs
Chapter 2 discussed two types of customer behavior models: CBMGs and Customer Visit Models (CVMs). In a CVM, each session is characterized by the number of visits to each state of the CBMG. For example, consider Table 11.2 that shows the CVM for twelve sessions for the same states as in the CBMG of Fig. 11.4. We do not include VEntry and vExit in the table because they are always equal to one.
Sessions represented by a CVM instead of a CBMG can be obtained from an HTTP log through the algorithm GetCVMSessions shown in Fig. 11.9.

Again, as in the case of sessions characterized ...
