Cumulative mass distribution
WebA cumulative distribution function (CDF) describes the probabilities of a random variable having values less than or equal to x. It is a cumulative function because it sums the total likelihood up to that point. Its output always ranges between 0 and 1. CDFs have the following definition: CDF (x) = P (X ≤ x) WebDifferential mass distribution is represented by a histogram and a "middle of cut-off diameters" method in Fig. 2 as it was described by Majoral et al. 42 On average 50% of the particulate mass in ...
