The company is under pressure from the U.S. Department of Justice to turn over a sample of search queries from its closely guarded database.
Three of the metaheuristics include chaotic adjustments to dynamic stochastic sampling of search metrics distributions (fat-tailed and other, highly non-linear, stepped ranges).
A federal judge told the Justice Department that it can expect to get at least some of the information sought from Google, but expressed reservations about requiring the company to hand over a random sample of search requests.
The sample of search terms were used to derive a single RSV trend for their related concept.
Different strategies are based on a statistical sampling of search space by ad-hoc Monte Carlo methods [ Liu, 2002], such as the so-called Gibbs sampling method [ Lawrence et al. 1993], or by maximization of proper scoring or likelihood functions.
Because only a sample of searches is used and searches for which there are insufficient observations are excluded, Google Trends data could be affected by sample bias (in small samples, only random draws with enough observations are shown) (Kearney and Levine 2015).
A single search was used for both stages of the review with no methodological restrictions (for a sample of searches see Additional file 1).
Alternative specifications of the root terms, e.g. "stop smoking" for smoking cessation, resulted in a similar sample set of search terms, suggesting the analysis is not dependent on the initial search term selection.
It will consist of an orbiter and several landers, one of which will analyze soil samples to search for traces of life on Mars.
By contrast to direct BLAST searches [ 36], we used two rounds of BLAST searches against a local environmental database, comprising 9,865,367 predicted ORFs from about 33 million sequences from 236 metagenomic samples, to search for homologs of the cultured sequences of these conserved families.
