Students will learn methods of statistical analysis of experimental data, fitting of theoretical models, estimation of parameters, how to estimate uncertainties of model parameters, Monte Carlo modeling, and testing of hypothesis. Another important topic is searching for periods in time series of observed data. The lecture is focused on practical applications in Astronomy and Astrophysics.
