Reliability assumption
WebA complete and adequate assessment of validity must include both theoretical and empirical approaches. As shown in Figure 7.4, this is an elaborate multi-step process that must take into account the different types of scale reliability and validity. Figure 7.4.

Reliability is evaluated using the S/N curve that produces the same damage sum at its retirement time when load and usage are applied in distributions. The method does not require selection of a reference S/N curve or the weighted reliability assumption. It is easier to understand and implement from a

However I don’t think that the concept of a total score really applies, although I may be wrong. Tukey’s test of non-additivity tests the null hypothesis that there is no multiplicative interaction between cases and items. Could ...
