41Studentized residual — In statistics, a studentized residual, named in honor of William Sealey Gosset, who wrote under the pseudonym Student , is a residual adjusted by dividing it by an estimate of its standard deviation. Studentization of residuals is an important… …
42Robust statistics — provides an alternative approach to classical statistical methods. The motivation is to produce estimators that are not unduly affected by small departures from model assumptions. Contents 1 Introduction 2 Examples of robust and non robust… …
43Mean difference — The mean difference is a measure of statistical dispersion equal to the average absolute difference of two independent values drawn from a probability distribution. A related statistic is the relative mean difference, which is the mean difference …
44Bimodal distribution — Bimodal redirects here. For the musical concept, see Bimodality. Figure 1. A simple bimodal distribution, in this case a mixture of two normal distributions with the same variance but different means. The figure shows the probability density… …
45Maximum entropy probability distribution — In statistics and information theory, a maximum entropy probability distribution is a probability distribution whose entropy is at least as great as that of all other members of a specified class of distributions. According to the principle of… …
46nature, philosophy of — Introduction the discipline that investigates substantive issues regarding the actual features of nature as a reality. The discussion here is divided into two parts: the philosophy of physics and the philosophy of biology. In this… …
47Statistical dispersion — In statistics, statistical dispersion (also called statistical variability or variation) is variability or spread in a variable or a probability distribution. Common examples of measures of statistical dispersion are the variance, standard… …

49Hair analysis (alternative medicine) — Hair analysis is the chemical analysis of a hair sample. It is used in some branches of alternative medicine as a method of investigation to assist diagnosis. Its use is controversial. Background In hair analysis the levels of minerals and metals …
50Standard score — In statistics, a standard score is a dimensionless quantity derived by subtracting the population mean from an individual raw score and then dividing the difference by the population standard deviation. This conversion process is called… …
