PSTf-class

The class <code>"PSTf"</code> is the flat representation of a probabilistic suffix tree (PST) storing a variable length Markov chain model. The flat representation is a list where each element corresponds to a given depth. It is the prefered representation and is used by all functions for model fitting and sequence analysis with PST. The nested representation <code>"<links4class>PSTr</links4class>"</code> is used only for printing and plotting PSTs.

This package provides functions to analyse state sequences
        with probabilistic suffix trees (PST), the construction that
        stores variable length Markov chains (VLMC). The PST library
        allows to learn VLMC models and includes many additional tools
        and features to analyse sequence data with these models:
        visualization tools, functions for model optimization, for
        sequence prediction and artificial sequences generation,
        context and pattern mining. The package is specifically adapted
        to the field of social sciences by allowing to learn VLMC
        models from sets of individual sequences possibly containing
        missing values and to account for case weights. The library
        also allows to fit segmented VLMC, where conditional transition
        probabilities are estimated and stored for each value of a
        covariate. This software results from research work executed
        within the framework of the Swiss National Centre of Competence
        in Research LIVES, which is financed by the Swiss National
        Science Foundation. The authors are grateful to the Swiss
        National Science Foundation for its financial support.
