qq.logis.rayleigh: Quantile versus quantile (QQ) plot for the...

In reliaR: Package for some probability distributions.

Description

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

Usage

qq.logis.rayleigh(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.logis.rayleigh() carries out a QQ plot for the Exponetial Extension.
