mdlMLE | R Documentation |
Support function for computing statistics for left-censored data using the maximum likelihood method (Helsel and Cohn, 1988).
mdlMLE(x, method = "MLE", alpha = 0.4)
x |
the data to estimate, Missing values permitted and ignored. Must be an object of class "lcens," a numeric vector, or the output from censpp. |
method |
the method to use, either "MLE" or "log MLE." |
alpha |
the offset for plotting position, used to compute the filled in values. |
A list containing the mean and standard deviation, filled in
values for the censored values, and the censored levels. If method
is "log MLE," then the list also contains the mean and standard deviation of the
natural log-transformed values computed by maximum likelihood.
