The Good–Toulmin (GT) estimator was developed by Good and Toulmin in 1953. [4] The estimate of the unseen species based on the Good–Toulmin estimator is given by U GT ≜ U GT ( X n , t ) ≜ − ∑ i = 1 ∞ ( − t ) i φ i . {\displaystyle U^{\text{GT}}\triangleq U^{\text{GT}}(X^{n},t)\triangleq -\sum _{i=1}^{\infty }(-t)^{i}\varphi _{i}.}
A Toulmin argument diagram, redrawn from his 1959 Uses of Argument A generalised Toulmin diagram. Stephen Toulmin, in his groundbreaking and influential 1958 book The Uses of Argument, [22] identified several elements to an argument which have been generalized. The Toulmin diagram is widely used in educational critical teaching.
Stephen Edelston Toulmin (/ ˈ t uː l m ɪ n /; 25 March 1922 – 4 December 2009) was a British philosopher, author, and educator.Influenced by Ludwig Wittgenstein, Toulmin devoted his works to the analysis of moral reasoning.
Toulmin argumentation framework example. As demonstrated in Toulmin’s argumentation framework, the grounds of an assumption require warrant and backing to legitimize the claim and prove the soundness of the conclusion. The framework involves a claim, grounds, warrant, qualifier, rebuttal, and backing. The initial claim of an argument is the ...
Uncertainty quantification (UQ) is the science of quantitative characterization and estimation of uncertainties in both computational and real world applications. It tries to determine how likely certain outcomes are if some aspects of the system are not exactly known.
The hypothetico-deductive model or method is a proposed description of the scientific method. According to it, scientific inquiry proceeds by formulating a hypothesis in a form that can be falsifiable, using a test on observable data where the outcome is not yet known. A test outcome that could have and does run contrary to predictions of the ...
Mark and recapture is a method commonly used in ecology to estimate an animal population's size where it is impractical to count every individual. [1] A portion of the population is captured, marked, and released. Later, another portion will be captured and the number of marked individuals within the sample is counted.
Species diversity is the number of different species that are represented in a given community (a dataset). The effective number of species refers to the number of equally abundant species needed to obtain the same mean proportional species abundance as that observed in the dataset of interest (where all species may not be equally abundant).
