True or false? an unbiased estimator is preferable to an efficient estimator
Step by step
Solved in 2 steps
- True or False: Explain For a difference-in-differences estimator to be valid, outcome trends must be parallel and balanced (i.e., equivalent).A researcher is interested in the impact of joining a weight loss program in the past 12 months on the individuals weight loss. The analysis was restricted to people aged 16 and olders who answered yes to the question "During the past 12 months, have you tried to lose weight?" About 5% of the sample had joined a weight loss program in the past year. The researcher has decided to use propensity score analysis. What would be the appropriate estimator for this analysisWhat do you mean by Instrumental Variables Estimators in relation to quasi-experiment?
