MittagLeffleR (version 0.4.1)

logMomentEstimator: Log-Moments Estimator for the Mittag-Leffler Distribution (Type 1).

Description

Tail and scale parameter of the Mittag-Leffler distribution are estimated by matching with the first two empirical log-moments (see Cahoy et al., 10.1016/j.jspi.2010.04.016).

Usage

logMomentEstimator(x, alpha = 0.05)

Arguments

x

A vector of non-negative data.

alpha

Confidence intervals are calculated at level 1 - alpha.

Value

A named vector with entries (nu, delta, nuLo, nuHi, deltaLo, deltaHi) where nu is the tail parameter and delta the scale parameter of the Mittag-Leffler distribution, with confidence intervals (nuLo, nuHi) resp. (deltaLo, deltaHi).
