system of simultaneous equations
81Gauss elimination — ▪ mathematics in linear and multilinear algebra, a process for finding the solutions of a system of simultaneous linear equations by first solving one of the equations for one variable (in terms of all the others) and then substituting this …
82Negative and non-negative numbers — A negative number is a number that is less than zero, such as −2. A positive number is a number that is greater than zero, such as 2. Zero itself is neither positive nor negative. The non negative numbers are the real numbers that are not… …
83Finite-difference time-domain method — Finite difference time domain (FDTD) is a popular computational electrodynamics modeling technique. It is considered easy to understand and easy to implement in software. Since it is a time domain method, solutions can cover a wide frequency… …

85Gauss–Newton algorithm — The Gauss–Newton algorithm is a method used to solve non linear least squares problems. It can be seen as a modification of Newton s method for finding a minimum of a function. Unlike Newton s method, the Gauss–Newton algorithm can only be used… …
86Multiple comparisons — In statistics, the multiple comparisons or multiple testing problem occurs when one considers a set of statistical inferences simultaneously.[1] Errors in inference, including confidence intervals that fail to include their corresponding… …
87Ronald Fisher — R. A. Fisher Born 17 February 1890(1890 02 17) East Finchley, London …
88Confidence interval — This article is about the confidence interval. For Confidence distribution, see Confidence Distribution. In statistics, a confidence interval (CI) is a particular kind of interval estimate of a population parameter and is used to indicate the… …
89Democratic peace theory — (or liberal democratic theory[1] or simply the democratic peace ) is the theory that democracies, for some appropriate definition of democracy, rarely, or even never, go to war with one another. Some have preferred the term inter democracy… …
90Methods engineering — Not to be confused with Method engineering in the field of information systems. Methods engineering is a subspecialty of Industrial engineering concerned with human integration in industrial production processes.[1] Contents 1 Overview 2 Methods… …
