Natural time analysis is a statistical method applied to analyze complex time series and critical phenomena, based on event counts as a measure of "time" rather than the clock time.[1][2] Natural time concept was introduced by P. Varotsos, N. Sarlis and E. Skordas in 2001.[3] Natural time analysis has been primarily applied to earthquake prediction[1][2] / nowcasting[4][5][6][7][8][9][10][11][12][13] and secondarily to sudden cardiac death[14] / heart failure[15][16] and financial markets.[17] Natural time characteristics are considered to be unique.[9]
