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 ...

By Courtney Kennedy, Andrew Mercer, Scott Keeter, Nick Hatley, Kyley McGeeney and Alejandra Gimenez As the costs and nonresponse rates of traditional, probability-based surveys seem to grow each year, ...

The paper shows that under very broad conditions the usual theorems concerning the limiting distributions of estimates hold for estimates based on samples selected from finite universes, at random ...

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 ...

The jackknife estimation procedure is used to estimate Brillouin's and Simpson's indices of diversity when sampling is done by selecting quadrats. Using simulated data, a sampling plan is set up to ...

Suppose you buy a major asset like a new piece of machinery. Under standard accounting rules, you cannot write off the cost of the machinery in the year you incur the expense. Rather, you have to ...

SHANGHAI, China – Scientists using DNA samples have doubled their estimates of the wild panda population in a nature sanctuary in China, in a finding they say bodes well for the survival of one of the ...
