WebMar 31, 2024 · As described in Section 2.3, we use empirical cumulative distribution function based on distributions over 1901–2007 and over 1901–2024 to examine if there is a change in length of return period. The estimations were based on large samples, 107 years and 119 years of data respectively, to ensure that estimation errors related to small ... Weba standard empirical cdf (ecdf) gives little information about the tails of the data when there are extreme values. Details The transform is nonparametric: linear in the middle of the data and matched to a log-log transform on the tails, where the tail regions are determined by quantiles.
