MMP.19:8 - Common Anti-Patterns and How to Avoid Them

Recognizable failure	Repair
Use the population input law after receiving information about the case.	Condition under the factual account before evaluating its alternative response.
Independently simulate two marginals and interpret the pairs as the same units.	Construct or bound the joint response law the interpretation needs.
Replace a nested intermediate value by its population mean.	Compute the intermediate response for each common input before evaluating the outer mechanism.
Report a uniquely identified answer because one chosen model yields a number.	Examine the target across the admissible models, or report the result as conditional on that model.
Demand a benefit probability for a choice determined by expected outcomes.	Recover the criterion and use the sufficient marginal comparison.
