Evaluation of Client Status for Likelihood of Churn
First Claim
1. A method of evaluating client status, comprising:
- receiving client data representing events from a set of different event types performed by clients;
estimating, using a computer and based on the client data, parameters of a statistical model that describes client behavior, wherein a chum type of event is encoded in the statistical model as an absorbing state of a stochastic process, with a time of transition to the absorbing state modeled as being infinite, and wherein at least one of the parameters corresponds to the churn type of event; and
calculating a likelihood of churn for a plurality of the clients at one or more time points using the statistical model and its estimated parameters.

Abstract
System, including method, apparatus, and computer-readable media, for evaluating client status for a likelihood of churn. Client data may be received, with the client data representing events from a set of different event types performed by clients. Parameters of a statistical model that describes client behavior may be estimated using a computer and based on the client data. A churn type of event may be encoded in the statistical model as an absorbing state of a stochastic process, with a time of transition to the absorbing state modeled as being infinite. At least one of the parameters may correspond to the churn type of event. A likelihood of churn may be calculated for a plurality of the clients at one or more time points using the statistical model and its estimated parameters.

9. An article comprising at least one computer readable storage medium containing instructions executable by a computer to perform a method of evaluating client status, the method comprising:
-
receiving client data representing events from a set of different event types performed by clients; estimating, using a computer and based on the client data, parameters of a statistical model that describes client behavior, the statistical model being based on an assumption that the events for each client form a sequence of event types that follows a Markov chain, wherein a churn type of event is encoded in the statistical model as an absorbing state of a stochastic process, with a time of transition to the absorbing state modeled as being infinite, and wherein at least one of the parameters corresponds to the churn type of event; and calculating a likelihood of churn for a plurality of the clients at one or more time points using the statistical model and its estimated parameters. - View Dependent Claims (10, 11, 12, 13, 14, 15)
