JUDGMENTCONFIDENCEFormal expert elicitation is a widely used method for quantifying uncertain variables in decision and risk analysis. When estimating uncertain variables, experts and laypeople exhibit overprecision, meaning that the ranges of their estimates are too narrow. Overprecision, a form of ...

Discrete Variables Discrete variablescan only take on a set number of values [2]. They are easily countable within a fixed t...
If, as Bridgman held, the meaning of a concept is the set of operations used to specify it, then measurement is the ‘assignment of numerals to objects or events according to rules’ (Stevens 1951, p. 1) and the attribute measured via any such assignment is defined by the rules used. ...
(fMRI). Given novel brain recordings, this decoder generates intelligible word sequences that recover the meaning of perceived speech, imagined speech and even silent videos, demonstrating that a single decoder can be applied to a range of tasks. We tested the decoder across cortex and found ...
Different substances in ocean have specific absorption spectra, meaning they absorb light at different wavelengths. For example, chlorophyll, a pigment found in marine plants and phytoplankton, absorbs light primarily in the blue and red parts of the spectrum while reflecting green light, giving the ...
Thus, the imprecision in the meaning of success/failure is quantified through the fuzzy success/failure membership function, which is defined over the performance characteristic variable. The proposed fuzzy reliability measures provide an alternative to model the continuous state behavior for a component ...
In practice, since F is an empirical distribution obtained through a forecasting model, the corresponding random variable X has a compact support, meaning that there is only a finite number of points where P[X=x]>0. Also, all values of x are discrete numbers. Thus, the integrals can be ...

To make a clear distinction, use the contrasting terms intermittent and uninterrupted.] Not to be confused with: continual –intermittent; often...
