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.
Usci(ylo, yhi, rnk = TRUE)The lower end of the concentration interval
The upper end of the concentration interval
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.
Returns a single column of uscores or the ranks of uscores for a single pair of (low, high) interval-censored data columns.
