Normal Distribution with MLE Solution |

This example validates the calculations for the variance and covariance matrix for a Normal distribution with ML estimates in Weibull++ standard folios.

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

Results in Weibull++

The following picture shows the results in Weibull++.
