Usage

Arguments

x

Numeric. Vector of thresholds at which the local Pareto alpha is calculated.

distribution

Character.

  • 'lnorm' for lognormal distribution (arguments: meanlog, sdlog)

  • 'norm' for normal distribution (arguments: mean, sd)

  • 'gamma' for gamma distribution (arguments: shape, rate, scale)

  • 'weibull' for weibull distribution (arguments: shape, scale)

  • 'exp' for exponential distribution (arguments: rate)

  • 'Pareto' for Pareto distribution (arguments: t, alpha, truncation = NULL)

  • 'GenPareto' for exp distribution (arguments: t, alpha_ini, alpha_tail, truncation = NULL)

  • 'PiecewisePareto' for exp distribution (arguments: t, alpha, truncation = NULL, truncation_type = 'lp')

...

Arguments for the selected distribution

Value

Local Pareto alpha of the selected distribution at x
