Implementation Science and Evidence-to-Practice Translation
Q: Comparative effectiveness research compares real-world outcomes of different treatments.
Did You Know?
Yes. If the true disturbance term has a nonzero mean, that nonzero part is absorbed into the intercept in the estimated equation. The slope estimator is unaffected and remains unbiased. The intercept estimator will be biased for the original intercept but unbiased for the combined intercept (original intercept plus μ).
