A Non-parametric Statistical Approach on the Classification of Photometric Time Series Data    [PDF]

Noble P. Abraham
We present a non-parametric statistical approach on the classification of transient events based on photometric observations. The time series data of blazars, CVs, Mira variables and supernovae from Catalina Real-Time Transient Survey (CRTS) are used in the analysis discussed in this paper. For each class of object, templates are generated with which a correlation analysis is carried out and statistics derived. Based on the derived statistics the test object is assigned a class. Templates were constructed using random sampling and bootstrap sampling techniques. We discuss the trends of misclassification, in the classification based on the templates constructed from the available dataset, and on the ability of the templates to distinguish between the classes.
