Lecture 4: Decision making

Question 1

Compensatory rule

Answer 1

• criterion is predicted by weighted sum of a number of predictors
• total score can result from different combinations

Question 2

Disjunctive rule

Answer 2

• special case of compensatory rule
• one accomplished threshold suffices (for complete compensation)
• often met in clincal settings

Question 3

Conjunctive rule

Answer 3

• no compensation possible
• more strict model

Question 4

Mixture Form (1)

Answer 4

1. Weak conjuctive rule - all predictors must surpass a pre-specified treshold
2. Beyond these boundaries utilization of a compensatory rule

Question 5

Mixture Form (2)

Answer 5

1. Weak disjuctive rule - positive diagnosis if a treshold in either predictor is surpasses
2. Below these boundaries compensatory rule
