The default Reliability Growth report is the Observed Data report, which contains the Cumulative Events plot, the Mean Time Between Failures plot, and the Duane plot. These are shown in Observed Data Report, where we have opened the Mean Time Between Failures report. To produce this report, follow the instructions in Example Using the Reliability Growth Platform.

The Intercept value is given, for historical reasons, as the intercept for a fit in the natural logarithmic scale. Specifically, the natural logarithm of Cumulative MTBF is regressed on the natural logarithm of Time to Event. The value of Intercept is the value predicted by this regression equation at log(1) = 0, where log is the natural logarithm. To obtain the intercept for a fit in terms of base 10 logarithms, divide the Intercept value by log(10). See Chapter 13 of Tobias and Trindade (2012).
