Usci: Interval-censored U-Score

In NADA2: Data Analysis for Censored Environmental Data

Interval-censored U-Score

Description

Interval-censored computation of uscores and their ranks for 1 parameter. Called by uscoresi. Usci is not expected to be of much use to users on its own.

Usage

Usci(ylo, yhi, rnk = TRUE)

Arguments

ylo	The lower end of the concentration interval
yhi	The upper end of the concentration interval
rnk	A TRUE/FALSE variable on whether to compute the multivariate pattern on the uscores, or the ranks of the uscores. Default is rnk=TRUE, use the ranks. rnk = FALSE returns the uscores.

Value

Returns a single column of uscores or the ranks of uscores for a single pair of (low, high) interval-censored data columns.

Examples

data(Brumbaugh)

# for demonstration purposes create a lower end concentration interval
Brumbaugh$lowHg<-Brumbaugh$Hg*(1-Brumbaugh$HgCen)

with(Brumbaugh,Usci(lowHg,Hg))
