Interpretation summary for Nonparametric Growth Curve

Use nonparametric growth curves to analyze data from a repairable system without making assumptions about the distribution of successive failure (or repair) times.

You can estimate growth curves of the mean cost of maintaining the system or the mean number of repairs over time. You can then determine whether a trend exists in times or costs between successive failures and whether system failures or costs are becoming more frequent, less frequent, or remaining constant.
