MME_WL: Estimating parameters in weighed Lindley distribution

Description

Parameter estimate functions: MME_WL, MMEm_WL, MLE_WL and MLEc_WL can be used to estimate parameters in weighed Lindley distribution. MME_WL, MMEm_WL and MLEc_WL have closed form values for parameters, lambda and phi. On the other hands, parameter lambda in MLE_WL is based on numerical solution. It use the function nleqslv for solving one variable equation.

Usage

MME_WL(x)
MMEm_WL(x)
MLEc_WL(x)

Value

A numeric vector of lambda and phi estimated by each method.

Arguments

x

a numeric vector.

Details

These functions implement formulas given in Hyoung-Moon Kim. et al. (2020).

Examples

data <- fail_fiber
mme <- MME_WL(data)
modified_mme <- MMEm_WL(data)
mle <- MLE_WL(data, mme[2])
mlec <- MLEc_WL(data)

rbind(mme, modified_mme, mle, mlec)
