Inverse distance weighting — (IDW) is a method for multivariate interpolation, a process of assigning values to unknown points by using values from usually scattered set of known points. A general form of finding an interpolated value u for a given point x using IDW is an… … Wikipedia
Methods of computing square roots — There are several methods for calculating the principal square root of a nonnegative real number. For the square roots of a negative or complex number, see below. Contents 1 Rough estimation 2 Babylonian method 2.1 Example … Wikipedia
Inverse function theorem — In mathematics, specifically differential calculus, the inverse function theorem gives sufficient conditions for a function to be invertible in a neighborhood of a point in its domain. The theorem also gives a formula for the derivative of the… … Wikipedia
Inverse quadratic interpolation — In numerical analysis, inverse quadratic interpolation is a root finding algorithm, meaning that it is an algorithm for solving equations of the form f ( x ) = 0. The idea is to use quadratic interpolation to approximate the inverse of f . This… … Wikipedia
Inverse problem — An inverse problem is a general framework that is used to convert observed measurements into information about a physical object or system that we are interested in. For example, if we have measurements of the Earth s gravity field, then we might … Wikipedia

Inverse probability — In probability theory, inverse probability is an obsolete term for the probability distribution of an unobserved variable. Today, the problem of determining an unobserved variable (by whatever method) is called inferential statistics, the method… … Wikipedia
Inverse scattering transform — In mathematics, the inverse scattering transform is a method for solving some non linear partial differential equations. It is one of the most important developments in mathematical physics in the past 40 years. The method is a non linear… … Wikipedia
inverse ratio ventilation — a type of assisted ventilation in which the length of inhalations is artificially increased until it is longer than the length of exhalations; it is believed to improve distribution of ventilation at lower airway inflating pressures and to… … Medical dictionary
