Notes: |
|
FV results used manually selected blocks of fixed values. |
|
EF results used blocks with functionally dependent factors described by embedded functions;
the functions were evaluated, and the blocks converted to fixed values, automatically. |
|
The Calendar, Constraint 1-4 and Shopping Cart examples used embedded functions
to insure test factor values conformed to their constraints. |
|
The Body Mass Index example used embedded functions to evaluate equivalence class factors;
the equivalence class factors insured (1) the design would reach selected classes of results and
(2) the classes would be paired with their nondeterminant factor values. |
|
The variable strength examples, VS, SCA and SCB, used embedded functions to evaluate hybrid factors;
hybrid factors combined the values of 2 or more test factors with each other.
Designs with higher strength subarrays were generated using associations among the hybrid factors and test factors. |
|
Examples with (t',k')=(2,k) are strength t=2 base cases for variable strength comparisons. |
|
SCA (2,18) is the same as the strength 2 Shopping Cart example. |
|
The SCA model has 5 allowed quantity values; SCB has 4. Otherwise the models are the same. |
