Hi all,
Our next virtual meeting will be at 12pm (EST) Wednesday, April 21,
where Kristen
Hunter <https://scholar.harvard.edu/khunter/home>(Harvard) will present
"Conceptualizing experimental controls using the potential outcomes
framework."
*Abstract*
The goal of a well-controlled study is to remove unwanted variation when
estimating the causal effect of the intervention of interest. Experiments
conducted in the basic sciences frequently achieve this goal using
experimental controls, such as "negative'' and "positive''
controls, which
are measurements designed to detect systematic sources of unwanted
variation. Here, we introduce clear, mathematically precise definitions of
experimental controls using potential outcomes. Our definitions provide a
unifying statistical framework for fundamental concepts of experimental
design from the biological and other basic sciences. We discuss
experimental controls as tools for researchers to wield in designing
experiments and detecting potential design flaws, including using controls
to diagnose unintended factors that influence the outcome of interest,
assess measurement error, and identify important subpopulations.
