Methods of the seismic risk analysis in either natural or induced seismicity can be divided into the parametric methods and the nonparametric ones. Within the presented work correlations between ten functions representing nonparametric traits of the local sequence of induced seismicity, a risk function issued from the parametric model and the number of strong events in the sequence were studied. The analysis showed that the parametric approach to time-varying processes like the triggered seismicity process may give more reliable results than the nonparametric inference.
