A Goodness of Fit test checks on whether your data are reasonable or highly unlikely, given an assumed distribution model | General tests for checking
the hypothesis that your data are consistent with a particular model are
discussed in Chapter 7. Details
and examples of the Chi-Square
Goodness of Fit test and the Kolmolgorov-Smirnov
(K-S) test are given in Chapter 1. The Chi-Square test can be used
with Type I or Type II censored data and
readout data if there are enough failures and readout times. The K-S
test generally requires complete samples, which limits its usefulness in
reliability analysis.
These tests control the probability of rejecting a valid model as follows:
