Credible regions are not unique, as any given probability distribution has an infinite number of -credible regions, i.e. regions of probability .For example, in the univariate case, there are multiple definitions for a suitable interval or region:
Confidence intervals are used to estimate the parameter of interest from a sampled data set, commonly the mean or standard deviation.A confidence interval states there is a 100γ% confidence that the parameter of interest is within a lower and upper bound.
Test validity is the extent to which a test (such as a chemical, physical, or scholastic test) accurately measures what it is supposed to measure.In the fields of psychological testing and educational testing, "validity refers to the degree to which evidence and theory support the interpretations of test scores entailed by proposed uses of tests". [1]
Validity is the main extent to which a concept, conclusion, or measurement is well-founded and likely corresponds accurately to the real world. [1] [2] The word "valid" is derived from the Latin validus, meaning strong.
Another way to represent intervals is described in Cormen et al. (2009, Section 14.3: Interval trees, pp. 348–354). Both insertion and deletion require O ( log n ) {\displaystyle O(\log n)} time, with n {\displaystyle n} being the total number of intervals in the tree prior to the insertion or deletion operation.
A tolerance interval (TI) is a statistical interval within which, with some confidence level, a specified sampled proportion of a population falls. "More specifically, a 100×p%/100×(1−α) tolerance interval provides limits within which at least a certain proportion (p) of the population falls with a given level of confidence (1−α)."
The addition x + a on the number line. All numbers greater than x and less than x + a fall within that open interval.. In mathematics, a real interval is the set of all real numbers lying between two fixed endpoints with no "gaps".
In psychometrics, criterion validity, or criterion-related validity, is the extent to which an operationalization of a construct, such as a test, relates to, or predicts, a theoretically related behaviour or outcome — the criterion.
