| mathematical computing | Computer-assisted interpretation and analysis of various mathematical functions related to a particular problem. (12 Dec 1998) |

| mathematical determinant | A formal algebraic operation on the terms of a square matrix of quantities, fundamental in solving multiple simultaneous equations and widely used in regression analysis, notably in epidemiology and quantitative genetics. If determinant is zero, the equations have no unambiguous solution. (05 Mar 2000) |
| mathematical genetics | The study of genetic traits by formal analysis, e.g., quantitative genetics, population dynamics, genetic epidemiology, modeling. (05 Mar 2000) |
| mathematical model | <epidemiology> A formal framework to convey ideas about the components of a host-parasite interaction. Construction requires three major types of information: (a) a clear understanding of the interaction within the individual host between the infectious agent and the host, (b) the mode and rate of transmission between individuals, and (c) host population characteristics such as demography and behaviour. Mathematical models can aid exploration of the behaviour of the system under various conditions from which to determine the dominant factors generating observed patterns and phenomena. They also aid data collection and interpretation and parameter estimation, and provide tools for identifying possible approaches to control and for assessing the potential impact of different intervention measures.

| mathematics | That science, or class of sciences, which treats of the exact relations existing between quantities or magnitudes, and of the methods by which, in accordance with these relations, quantities sought are deducible from other quantities known or supposed; the science of spatial and quantitative relations. Mathematics embraces three departments, namely: 1. Arithmetic. 2. Geometry, including Trigonometry and Conic Sections. 3. Analysis, in which letters are used, including Algebra, Analytical Geometry, and Calculus. Each of these divisions is divided into pure or abstract, which considers magnitude or quantity abstractly, without relation to matter; and mixed or applied, which treats of magnitude as subsisting in material bodies, and is consequently interwoven with physical considerations. Origin: F. Mathematiques, pl, L. Mathematica, sing, Gr. (sc) science. See Mathematic, and -ics. Source: Websters Dictionary (01 Mar 1998) |
