1. An analysis apparatus incorporated in a computer and configured to access and analyze the contents recorded in a history recording part that records access records to a plurality of access destinations accessed by user terminals via a communication network, the analysis apparatus comprising:

  • a history analysis part analyzing a trend of an access history for each unit period and deriving a latent trait indicating a latent possibility of access to a preset target access destination for each session from the contents recorded in the history recording part that records, for each session, an access history indicating an access or non-access to each of the plurality of access destinations and the preset target access destination, the preset target access destination being a subset destination of the plurality of access destinations indicating a level of completion relating to an access of one of the plurality of access destinations;

    a principal component analysis part analyzing principal components of a frequency distribution of the latent trait derived by the history analysis part for each unit period;

    a classification part classifying a correlation of the principal components for each unit period into a plurality of classes based on the analysis of the principal components;

    an event recording part recording, for each unit period, contents of one or more events executed to induce an access to the preset target access destination;

    a first generating part deriving a distribution of a latent trait for each principal component and generating a latent trait principal component table that stores a correspondence between each principal component and each latent trait;

    a second generating part generating a class construction ratio table that stores a correspondence between each class and a composition ratio of each principal component;

    a third generating part generating an event classification table that stores a correspondence between each class and the contents of each event; and

    an analysis result recording part recording the latent trait principal component table generated by the first generating part, the class construction ratio table generated by the second generating part and the event classification table generated by the third generating part, as an event feature model of an effect on execution of one of the one or more events.
