lmomRCmark {lmomco}

Sample L-moment for Right-Tail Censoring by a Marking Variable

Description

Compute the sample L-moments for right-tail censored data set in which censored data values are identified by a marking variable.

Usage

lmomRCmark(x, rcmark=NULL, r=1, sort=TRUE)

Arguments

x

A vector of data values.

rcmark

The right-tail censoring (upper) marking variable for unknown threshold: 1 is uncensored, 0 is censored.

r

The L-moment order to return, default is the mean.

sort

Do the data need sorting? The availability of this option is to avoid unnecessary overhead of sorting on each call to this function by the primary higher-level function lmomsRCmark.

Value

An R list is returned.

lambdas

Vector of the L-moments. First element is \hat{\lambda}^{(0,0)}_1, second element is \hat{\lambda}^{(0,0)}_2, and so on.

ratios

Vector of the L-moment ratios. Second element is \hat{\tau}^{(0,0)}, third element is \hat{\tau}^{(0,0)}_3 and so on.

trim

Level of symmetrical trimming used in the computation, which will equal NULL if asymmetrical trimming was used.

leftrim

Level of left-tail trimming used in the computation.

rightrim

Level of right-tail trimming used in the computation.

source

An attribute identifying the computational source of the L-moments: “lmomsRCmark”.
