pp.exp.power: Probability versus Probability (PP) plot for the Exponential...

In reliaR: Package for some probability distributions.

Description

The function pp.exp.power() produces a PP plot for the Exponential Power distribution based on their MLE or any other estimator. Also, a reference line can be sketched.

Usage

pp.exp.power(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.exp.power() carries out a PP plot for the Exponential Power distribution.
