1. “Essential” category: includes method parameters that are critical to the method output
and therefore require evaluation;
2. “Less important” category: includes method parameters that are not as critical as those
in the “Essential” category, but may still affect the method output. These parameters
should be evaluated at the scientist’s discretion;
3. “Depends on Method” category: includes parameters that may affect the method
output differently for different methods, such that these parameters should be treated
differently for each method;
4. “Not useful” category: includes method parameters that are known to have no impact
on the method output, such that these parameters need not be evaluated for
robustness.
