| regression of the mean | If, for a symmetrical population with a single mode, a measurement, selected because it is extreme, is repeated, on average the second reading will be closer to the mean than the first. (05 Mar 2000) |

| law of regression to mean | In a population mating at random, the progeny of a parent with an extreme value for a measurable phenotype will tend on average to have values nearer the population mean than in the extreme parent. See: law of regression to mean. Synonym: law of regression to mean. (05 Mar 2000) |

| regression | 1. A return to a former or earlier state. 2. A subsidence of symptoms or of a disease process. 3. <psychiatry> A return to earlier, especially to infantile, patterns of thought or behaviour, a characteristic of many mental disorders also exhibited by normal persons in many situations, for example feelings of helplessness and dependency in a patient with a serious physical illness. Origin: L. Regressio = a return (18 Nov 1997) |
| regression analysis | Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see linear models) the relationship is constrained to be a straight line and least-squares analysis is used to determine the best fit. In logistic regression (see logistic models) the dependent variable is qualitative rather than continuously variable and likelihood functions are used to find the best relationship. In multiple regression the dependent variable is considered to depend on more than a single independent variable. (12 Dec 1998) |

| arithmetic mean | The mean calculated by adding a set of values and then dividing the sum by the number of values. (05 Mar 2000) |
| calculated mean organism | A hypothetical organism whose characters are the means of both the positive and negative characters of the organism's which belong to the same taxon as the CMO, as opposed to the hypothetical mean. Organism. (05 Mar 2000) |
| geometric mean | The mean calculated as the antilogarithm of the arithmetic mean of the logarithms of the individual values; it can also be calculated as the nth root of the product of n values. (05 Mar 2000) |
| geometric mean diameter | A measure of the central tendency of particle size composition of substrate materials sometimes used as an index of the quality of spawning gravels. Also referred to as D50 size. (09 Oct 1997) |
| mean | <statistics> Average value calculated by taking the sum of all values and dividing by the total number of values. (05 Jan 1998) |
| mean annual increment | The annual average growth rate for a tree, computed over its entire life cycle. (05 Dec 1998) |
