pp.moee: Probability versus Probability (PP) plot for the Marshall-Olkin Extended Exponential(MOEE) distribution

Description

The function pp.moee() produces a PP plot for the MOEE based on their MLE or any other estimate. Also, a reference line can be sketched.

Usage

pp.moee(x, alpha.est, lambda.est, main = " ", line = 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

logical; if TRUE, a 45 degree line is sketched.

...

additional arguments to be passed to the underlying plot function.

Value

The function pp.moee() carries out a PP plot for the MOEE.
