Goodness-of-fit tests for the power-law process based on the TTT-plot

The total-time-on-test plot (TTT-plot) and its theoretical counterpart, the scaled TTT-transform, are reviewed. It is shown how the TTT-plot can be used as a basis for goodness-of-fit tests for the power-law process when data are available from a repairable system. Both a subjective graphical procedure and an analytical test procedure based on the cumulative TTT-statistic are studied.<
