This article mainly introduces some basic click Model, these different click model to the user and search results page interaction behavior make different assumptions.To define a model, we need to describe the observed Variables,hidden variables, and the associations between them, and their dependencies on model parameters. After we have obtained the model parameters, we can make a CTR estimate, or calculate the maximum likelihood estimate of the data.1. RANDOM CLICK MODEL (RCM)This is the simpl
