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
The failure times of the 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]
