gev.d.init

obtain initial values by fitting every duration separately

internal

Intensity-duration-frequency (IDF) curves are a widely used analysis-tool
in hydrology to assess extreme values of precipitation
[e.g. Mailhot et al., 2007, <doi:10.1016/j.jhydrol.2007.09.019>].
The package 'IDF' provides functions to estimate IDF parameters for given
precipitation time series on the basis of a duration-dependent
generalized extreme value distribution
[Koutsoyiannis et al., 1998, <doi:10.1016/S0022-1694(98)00097-3>].
