freq.curve.gld {lmomco} | R Documentation |
This function returns the quantiles of the Generalized Lambda distribution given a vector of nonexceedance probabilities and the parameters of the distribution. Because in magnitude and frequency analysis the frequency curve is typically the objective, this is a convenient function to increase analysis efficiency.
freq.curve.gld(fs, para)
fs |
Vector of nonexceedance probabilities. |
para |
Parameters of the distribution as from vec2par . |
A vector of quantiles for the distribution.
This function assumes that the parameters are already confirmed as valid for the GLD distribution. A check is not made with successive calls to quagld
; this is done primarly for speed purposes. Therefore, when quagld
is called the paracheck=FALSE
options to that function is made.
