Normal Distribution with MLE Solution

This example compares the variance and covariance matrix for a Normal distribution with ML estimates.


Reference Case

The data set is from Example 4.17 on page 246 in the book Reliability Engineering by Dr. Elsayed, Addison Wesley Longman, Inc, 1996.


Data

Failure times of components are: 14, 18, 18, 20, 21, 22, 22, 20, 17, 17, 15, 13.


Result

[math]\displaystyle{ \Gamma ^{1} = \begin{bmatrix} 0.700 & 0\\ 0 & 0.350 \end{bmatrix}\,\! }[/math]
