Abstract

In this article, the principle of maximum likelihood estimation (MLE) is introduced. It is illustrated by an application of the maximum likelihood method for the estimation of the mean and standard deviation of a single censored data set. This is a data set for which some data are only known to be below a lower limit (left-censored) or above an upper limit. An example of the determination of an impurity in a raw material, where the measurements are carried out around the detection limit and some fall below it, is given to illustrate the application of MLE to a single censored data set.
