Probability versus Probability (PP) plot for the Logistic-Rayleigh(LR) distribution

Share:

Description

The function pp.logis.rayleigh() produces a PP plot for the Logistic-Rayleigh(LR) based on their MLE or any other estimate. Also, a reference line can be sketched.

Usage

1
pp.logis.rayleigh(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.logis.rayleigh() carries out a PP plot for the Logistic-Rayleigh(LR).
