Fig 4. Lack of significant increasing trends of indicators for DJI data for the duration 17/09/2011 to 16/09/2015.

Fig 4

Parameters used to analyze data are same as in Fig 1. The insets show a distribution of Kendall-τ for the corresponding indicator obtained by a parameter scan of over 1.25 million combinations. Lack of consistent value in Kendall−τ and relatively high p-values (> 0.1) for all EWS suggest that there are no clear trends. For the inset: x-axis scale is from −1 to 1 and the y-axis is from 0 to 0.11 (See Methods B).
