Misclassification Analysis
Slide 1 of 5
Misclassification Parameters
For binary variables, misclassification is characterized by:
| Parameter | Definition |
|---|---|
| Sensitivity (Se) | P(classified + |
| Specificity (Sp) | P(classified - |
For non-differential misclassification:
- Se and Sp are same for exposed and unexposed (or cases and controls)
For differential misclassification:
- Se and Sp differ by exposure or outcome status
