WebbOne way to do that is to find the exponential distribution whose cumulative distribution function (CDF) best approximates (in a sense to be explained below) the ECDF of the data. The exponential CDF is p = Pr {X <= x} = 1 - exp (-x/mu). Transforming that to -log (1-p)*mu = x gives a linear relationship between -log (1-p) and x. Webb24 jan. 2024 · The CDF ranges from 0 to 1. Method 1: Using the histogram CDF can be calculated using PDF (Probability Distribution Function). Each point of random variable will contribute cumulatively to form CDF. Example : A combination set containing 2 balls which can be either red or blue can be in the following set. {RR, RB, BR, BB} t -> No of red balls.
