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”.
