Is the distribution parameter object consistent with the corresponding distribution? The distribution functions (cdfgep
, pdfgep
, quagep
, and
lmomgep
) require consistent parameters to return the cumulative
probability (nonexceedance), density, quantile, and L-moments of the distribution,
respectively. These functions internally use the are.pargep.valid
function. The parameters must be \(\beta > 0\), \(\kappa > 0\), and \(h > 0\).
