Description: P4J
        ===
        
        **Description**
        
        P4J is a python package for periodicity analysis of irregularly sampled
        time series based on Information Theoretic objective functions. P4J was
        developed for astronomical light curves, irregularly sampled time series
        of stellar magnitude or flux. These routines are build on the concept of
        **correntropy** [1], a generalized correlation function that
        incorporates higher order statistics of the process, lifting the
        assumption of Gaussianity. Correntropy has been used in astronomical
        time series problems in [2, 4].
        
        **Contents**
        
        -  Regression using the Weighted Maximum Correntropy Criterion (WMCC)
        -  Robust periodogram based on WMCC
        -  False alarm probability for periodogram peaks based on extreme value
           statistics
        -  Basic synthetic light curve generator
        
        **Instalation**
        
        ::
        
            pip install P4J
        
        **Example**

        **TODO**
        
        -  Cython backend for WMCC
        -  Multidimensional time series support
