  • for erosion models and basin types, and patterns of their cumulative frequency curves on a lognormal-probability chart were used to test the models. In order to achieve a better agreement with the observed field data, more realistic and comprehensive
  • Lognormal extrapolation and income estimation for poor Black families
  • Aspects of the lognormal function in the analysis of regional population distribution
  • formed during the Holocene and the rest, 40%, formed during the Pleistocene. Mean fan slopes for both all the Quaternary fans follow a lognormal frequency distribution. The area and relief ratio of the source area, which correlate well with the fan slope
  • , also follow a lognormal distribution, indicating the dimensions of fan/basin systems vary gradually rather than abruptly.
  • . This model is based upon a rational frequency distribution for the dependence of tonnage on cut-off and average grade. For this purpose the straight lognormal transformation is rejected, and replaced by a logarithmic, three-parameter transformation of wider
  • This work aims to examine the influence of the variability of the initial apertures on dissolutional growth of fissures and the evolving cave systems. To this end, the initial apertures were spatially uncorrelated and lognormally distributed
  • A multi-scale dataset of 17 rainfall events collected simultaneously at 4 spatial scales within a small agricultural catchment in 2005-2006 is presented. Analysis using exploratory techniques and a two-step, zero-inflated lognormal mixed-effects
