qq.moee: Quantile versus quantile (QQ) plot for the Marshall-Olkin Extended Exponential(MOEE) distribution

Description

The function qq.moee() produces a QQ plot for the MOEE based on their MLE or any other estimate. Also, a line going through the first and the third quartile can be sketched.

Usage

qq.moee(x, alpha.est, lambda.est, main = " ", line.qt = FALSE, ...)

Arguments

x

vector of observations

alpha.est

estimate of the parameter alpha

lambda.est

estimate of the parameter lambda

main

the title for the plot

line.qt

logical; if TRUE, a line going by the first and third quartile is sketched.

...

additional arguments to be passed to the underlying plot function.

Value

The function qq.moee() carries out a QQ plot for the MOEE.
