An independent test of methods of detecting system states and bifurcations in time-series data

► We perform an independent (“blind”) test of the novel techniques of time series analysis. ► We provide statistical description of the test data of unknown origin. ► We model equivalent time series and compare their statistical properties with the test data. ► We finally compare proposed models with the test models and realise their close similarity. ► We suggest that blind testing should be adopted in the statistical community.
