A likelihood region is the set of all values of θ whose relative likelihood is greater than or equal to a given threshold. In terms of percentages, a p% likelihood region for θ is defined to be. [1] [3] [6] If θ is a single real parameter, a p % likelihood region will usually comprise an interval of real values.
The mean absolute difference (univariate) is a measure of statistical dispersion equal to the average absolute difference of two independent values drawn from a probability distribution. A related statistic is the relative mean absolute difference, which is the mean absolute difference divided by the arithmetic mean, and equal to twice the Gini ...
The relative change is independent of the unit of measurement employed; for example, the relative change from 2 to 1 m is −50%, the same as for 200 to 100 cm.The relative change is not defined if the reference value (v ref) is zero, and gives negative values for positive increases if v ref is negative, hence it is not usually defined for negative reference values either.
The Spearman correlation coefficient is defined as the Pearson correlation coefficient between the rank variables. [6] For a sample of size n, the n raw scores are converted to ranks , and is computed as. where. denotes the usual Pearson correlation coefficient, but applied to the rank variables, is the covariance of the rank variables, and are ...
Copy number variation is a type of structural variation: specifically, it is a type of duplication or deletion event that affects a considerable number of base pairs. [2] Approximately two-thirds of the entire human genome may be composed of repeats [3] and 4.8–9.5% of the human genome can be classified as copy number variations. [4]
Instead, assuming constant temperature, integrating gives the second barometric formula: P = P 0 e − M g z / R ∗ T {\displaystyle P=P_{0}e^{-Mgz/R^{*}T}} In this formulation, R * is the gas constant , and the term R * T / Mg gives the scale height (approximately equal to 8.4 km for the troposphere ).
