Warning
This learning outcome is considered optional in [OhioDoHEducation21]. We include it here but do not develop it.
Learning Outcome
Diagnose and repair shortcomings of a statistical model. Contrast the implications of a statistical model with subject matter knowledge to identify its shortcomings. Improve the model by introducing new predictors, by altering the probability distribution used in the model, or by creating a more complex probability structure.
Sample Tasks
Contrast the implications of a statistical model with subject matter knowledge to identify flaws in the model.
Incorporate a new predictor into the model to reflect subject matter knowledge.
Replace one probability distribution with another to modify the model.
Introduce an additional component of variation to create dependence in observed data.
