theory of sampling
11Sampling variogram — In mathematical statistics, a sampling variogram is a graph that shows where a significant degree of causality (in this context, spatial dependence in sample spaces or sampling units) dissipates into randomness. A sampling variogram is obtained… …
12Sampling design — In the theory of finite population sampling, a sampling design specifies for every possible sample its probability of being drawn.Mathematically, a sampling design is denoted by the function P(S) which gives the probability of drawing a sample S …
13Sampling fraction — In sampling theory, sampling fraction is the ratio of sample size to population size.The formula for the sampling fraction is = n/N where n is the sample size and N is the population size. If the sampling fraction is less than 5%, then ignore the …
14Nyquist–Shannon sampling theorem — Fig.1: Hypothetical spectrum of a bandlimited signal as a function of frequency The Nyquist–Shannon sampling theorem, after Harry Nyquist and Claude Shannon, is a fundamental result in the field of information theory, in particular… …
15Gy's sampling theory — is a theory about the sampling of materials, developed by Pierre Gy in articles and books including:*(1960) Sampling nomogram *(1979) Sampling of particulate materials; theory and practice *(1982) Sampling of particulate materials; theory and… …
16Grounded theory — (GT) is a systematic methodology in the social sciences involving the generation of theory from data.[1] It is mainly used in qualitative research, but is also applicable to quantitative data.[2] Grounded theory is a research method, which… …
17probability theory — Math., Statistics. the theory of analyzing and making statements concerning the probability of the occurrence of uncertain events. Cf. probability (def. 4). [1830 40] * * * Branch of mathematics that deals with analysis of random events.… …
18Unified neutral theory of biodiversity — The unified neutral theory of biodiversity and biogeography (here Unified Theory or UNTB ) is a theory and the title of a monograph [http://www.pupress.princeton.edu/titles/7105.html] by ecologist Stephen Hubbell. The theory aims to explain the… …
19Detection theory — Detection theory, or signal detection theory, is a means to quantify the ability to discern between signal and noise. According to the theory, there are a number of determiners of how a detecting system will detect a signal, and where its… …
