This report presents a simple table for maximum likelihood estimates of the parameters of a normal or lognormal life distribution when the data are analyzed before all test units fail. The report also presents a table of the large-sample variances and covariances of the parameter estimates the report shows how to use this table to obtain approximate confidence limits for the parameters and other quantities, such as failure probabilities. An example on the life of locomotive controls illustrates the use of the tables.
