I’ve launched a website on measurement, experimentation, and causal inference: danrschley.github.io/Measurement-... I built it to share methods ideas that are often taught separately, but are deeply connected in practice.

Even if the causal assumptions for mediation hold, statistical assumptions can fail. Features like skewed distributions or outliers can distort standard estimates. Our new paper details which data issues cause trouble and reviews methods built to handle them: dx.doi.org/10.1002/wics...
