Fig. 2: Similarity between self-reported behaviors.
From: Influence of living in the same home on biomonitored levels of consumer product chemicals

Similarity measured using centered Jaccard coefficient with bootstrapped 95% confidence intervals. Behaviors sorted by the Jaccard coefficient and exclude behaviors infrequently used or used by almost all participants (<10 users or <10 non-users). Participants were asked, “In the last 24 h, did you use this product [or do this activity]?”.
