How Does Caliper Matching Compare to Other Matching Techniques?
Caliper matching is one of several methods available for reducing bias in observational studies. Other techniques include nearest neighbor matching, Mahalanobis distance matching, and exact matching. Each method has its own strengths and weaknesses, and the choice of method depends on the specific research question and dataset. Caliper matching is particularly useful when a balance between bias reduction and sample size retention is needed.
