Weibull++ Standard Folio Plot Type Example
Weibull++ provides many useful plots. We will use this example to illustrate them. Assume we have the following failure data.
| Number in State | State F or S | State End Time |
| 2 | F | 20 |
| 3 | F | 45 |
| 4 | F | 89 |
| 2 | F | 100 |
| 5 | F | 123 |
| 15 | S | 150 |
| 20 | S | 200 |
Analyze the above data using MLE, 2P Weibull distribution, we have the following results.
Click on the Plot button, Weibull++ automatically shows the first plot probability plot.
- Probability Plot
You also can choose to display the confidence bounds on time, reliability, or both. Click on the Confidence Bounds… link.
Then click on OK,
Probability plot shows the predicted (the line) and observed probability of failure (the dots, calculated from non-parametric LDA). If the straight line can fit the dots well, it means the distribution in use is suitable for this data set.
Click on the Plot Type drop down list to view all the available plots.
We will explain each plot type in below.
- Reliability vs. Time Plot.
It shows how reliability changes with time. Similar to the probability plot, it has both the predicted and the observed reliability values on the plot.
- UnReliability vs. Time Plot.
