Any non-linear differentiable function, (,), of two variables, and , can be expanded as + +. If we take the variance on both sides and use the formula [11] for the variance of a linear combination of variables (+) = + + (,), then we obtain | | + | | +, where is the standard deviation of the function , is the standard deviation of , is the standard deviation of and = is the ...
The above expression makes clear that the uncertainty coefficient is a normalised mutual information I(X;Y). In particular, the uncertainty coefficient ranges in [0, 1] as I(X;Y) < H(X) and both I(X,Y) and H(X) are positive or null. Note that the value of U (but not H!) is independent of the base of the log since all logarithms are proportional.
The bounds often also enclose distributions that are not themselves possible. For instance, the set of probability distributions that could result from adding random values without the independence assumption from two (precise) distributions is generally a proper subset of all the distributions enclosed by the p-box computed for the sum. That ...
The uncertainty theory invented by Baoding Liu [1] ... if there are multiple reasonable values that an uncertain measure may take, then the value as close to 0.5 as ...
In metrology, measurement uncertainty is the expression of the statistical dispersion of the values attributed to a quantity measured on an interval or ratio scale.. All measurements are subject to uncertainty and a measurement result is complete only when it is accompanied by a statement of the associated uncertainty, such as the standard deviation.
A disgraced Missouri teacher is scheduled to enter pleas next month to 19 charges alleging she paid her underage students for sex with cash, alcohol and marijuana and then attempted to intimidate ...
Farmers have a legal option for hiring labor with the H-2A visa program, which allows employers to bring in an unlimited number of seasonal workers if they can show there are not enough U.S ...
The Summary. Obesity dipped slightly in U.S. adults last year for the first time in more than a decade, a study found. The researchers suggested that might be due, in part, to the rise of weight ...
