Generally, we expect that surveys representing the same target population should produce estimates that are consistent with one another; that is, measures taken at roughly the same time should not ...
Robust estimates of overall immune-repertoire diversity from high-throughput measurements on samples
The diversity of an organism’s B- and T-cell repertoires is both clinically important and a key measure of immunological complexity. However, diversity is hard to estimate by current methods, because ...
Conflicting findings are often reported in microbiome association studies, which could be due to insufficient sample sizes and numerous confounders. A new study, utilizing two large-scale human ...
Survey mode effects linked to unit nonresponse and screening procedures were estimated in a study of self-reported tobacco, alcohol, and illicit drug use. Two samples of the same population were drawn ...
