freq.curve.glo: Frequency Curve of the Generalized Logistic Distribution

Description

This function returns the quantiles of the Generalized Logistic 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.

Usage

freq.curve.glo(fs, para)

Arguments

fs
Vector of nonexceedance probabilities.
para
Parameters of the distribution as from parglo.

Value

  • A vector of quantiles for the distribution.
