The statistical modelling of the textural properties of cave sediments using log skew Laplace distributions : Robin Hood's Cave, Creswell Crags, U.K.
Résumé
Modélisation statistique des propriétés texturales des sédiments de grotte en fonction des distributions log skew de Laplace. Cet article démontre l'utilité des distributions log skew de Laplace dans la modélisation des données granulométriques des sédiments de la grotte de Robin Hood, à Creswell Crags, U.K. Cette nouvelle approche a permis une reconstitution morphogénétique plus raffinée que les précédentes, tirées des méthodes habituelles.
Abstract
This paper demonstrates that log skew Laplace distributions can be used successfully to model particle size data from the cave sediments of Robin Hood's Cave, Creswell Crags, U.K. This new approach has led to the development of a more detailed geomorphic history of the cave than had been achieved previously with the use of standard procedures involving the estimation of low order sample moments for the same grain size data.
