tlmrray: Compute Select TL-moment ratios of the Rayleigh Distribution

Description

This function computes select TL-moment ratios of the Rayleigh distribution for defaults of $\xi = 0$ and $\alpha = 1$. This function can be useful for plotting the trajectory of the distribution on TL-moment ratio diagrams of $\tau^{(t_1,t_2)}_2$, $\tau^{(t_1,t_2)}_3$, $\tau^{(t_1,t_2)}_4$, $\tau^{(t_1,t_2)}_5$, and $\tau^{(t_1,t_2)}_6$. In reality, $\tau^{(t_1,t_2)}_2$ is dependent on the values for $\xi$ and $\alpha$.

Usage

tlmrray(trim=NULL, leftrim=NULL, rightrim=NULL, xi=0, alpha=1)

Arguments

trim

Level of symmetrical trimming to use in the computations. Although NULL in the argument list, the default is 0---the usual L-moment ratios are returned.

leftrim

Level of trimming of the left-tail of the sample.

rightrim

Level of trimming of the right-tail of the sample.

xi

Location parameter of the distribution.

alpha

Scale parameter of the distribution.

Value

An R list is returned.
