In the annex to the ocean-atmosphere boundary wave scattering, this problem becomes even more difficult, since the sea surface is mobile and its statistical ... WebMay 1, 1997 · The Gram Charlier distribution underestimates the peakedness of PDF in the range of very large slopes, but does not underestimate the skewness in the same range, thus causing a negative value of PDF. Therefore, the Gram Charlier distribution is also unsuitable to be used in the Eq. (1).

WebAug 1, 2024 · This paper offers a new approach to modeling the distribution of a portfolio composed of either asset returns or insurance losses. To capture the leptokurtosis, which is inherent in most financial series, data are modeled by using Gram-Charlier (GC) expansions.Since we are interested in operating with several series simultaneously, the … Webwhere n is the peakedness coefficient. The Liu PDF is an improvement over the Gram–Charlier distribution. It fits the Gram–Charlier distribution in the range of small slopes and works well in the full range of surface slopes. 4 However, the application of the Liu distribution is limited as the explicit expressions to determine the peakedness and … the pirate bаy vraie adresse
