- Ph = proportion of exposed subjects whose observed BNT scores: Yobs = Y + (X-
)a1 result in a positive shift in the slope - P'h = proportion of exposed subjects whose observed BNT scores: Yobs = Y - (X-)a2 result in a negative shift in the slope
- a1 = relative magnitude of misclassification (positive)
- a2 = relative magnitude of misclassification (negative)
)a1 result in a positive shift in the slope
