Incremental autocorrelations of ESS data for the first three waves (2011/12, 2013/14, and 2015/16) (a) and for the fourth wave (b). Graphs ‘a’ and’ b’ have one and two peaks (maximum values), respectively, and used as the threshold distance (distance band) in the hotspot analysis. (a) Incremental autocorrelation by distance band for ESS data, wave 1,2,3. (b) Incremental autocorrelation by distance band for ESS data, wave 4.
