Leave-p-out cross-validation (LpO CV) involves using p observations as the validation set and the remaining observations as the training set.This is repeated on all ways to cut the original sample on a validation set of p observations and a training set.
The Journal of AOAC International is a peer-reviewed scientific journal publishing research articles in the field of analytical chemistry and microbiology covering basic and applied research in analytical sciences related to foods, drugs, agriculture, the environment, and more. [1]
Taguchi methods (Japanese: タグチメソッド) are statistical methods, sometimes called robust design methods, developed by Genichi Taguchi to improve the quality of manufactured goods, and more recently also applied to engineering, [1] biotechnology, [2] [3] marketing and advertising. [4]
Halley's method is a numerical algorithm for solving the nonlinear equation f(x) = 0.In this case, the function f has to be a function of one real variable. The method consists of a sequence of iterations:
In the standard form of the equation (see later in article), and are respectively replaced by / and ; the advantage of this being that and have some understandable physical meaning, as they represent an integration time and a derivative time respectively.
In analytical chemistry, argentometry is a type of titration involving the silver(I) ion. Typically, it is used to determine the amount of chloride present in a sample. The sample solution is titrated against a solution of silver nitrate of known concentration.
ISO/IEC 17025 General requirements for the competence of testing and calibration laboratories is the main standard used by testing and calibration laboratories. In most countries, ISO/IEC 17025 is the standard for which most labs must hold accreditation in order to be deemed technically competent.
