Description

Support function for computing statistics for multiply-censored data extended from the "fill-in" probability plotting procedure method (Helsel and Cohn, 1988), now known as regression on order statistics.

Added from smwrQW.

Usage

1
mcenROS(x, method = "ROS", alpha = 0.4)

Arguments

x

the data to estimate, Missing values permitted and ignored. Must be an object of class "mcens," a numeric vector, or the output from censpp.

method

the method to use, either "ROS" or "log ROS."

alpha

the offset for plotting postion.

Value

A list containing the mean and standard deviation, filled in values for the censored values, and the censored levels. If method is "log ROS," then the list also contains the mean and standard deviation of the natural log-transformed values computed by regression on order statistics.
