pp.expo.logistic: Probability versus Probability (PP) plot for the...

In reliaR: Package for some probability distributions.

Description

The function pp.expo.logistic() produces a PP plot for the Exponentiated Logistic(EL) based on their MLE or any other estimate. Also, a reference line can be sketched.

Usage

pp.expo.logistic(x, alpha.est, beta.est, main = " ", line = FALSE, ...)

Arguments

x	vector of observations
alpha.est	estimate of the parameter alpha
beta.est	estimate of the parameter beta
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.expo.logistic() carries out a PP plot for the Exponentiated Logistic(EL).
