111Least squares — The method of least squares is a standard approach to the approximate solution of overdetermined systems, i.e., sets of equations in which there are more equations than unknowns. Least squares means that the overall solution minimizes the sum of… …
112Conservation biology — Biological conservation redirects here. For the journal, see Biological Conservation (journal). For the scientific journal, see Conservation Biology (journal). Efforts are being taken to preserve the natural characteristics of Hopetoun Falls,… …

114System identification — In control engineering, the field of system identification uses statistical methods to build mathematical models of dynamical systems from measured data. System identification also includes the optimal design of experiments for efficiently… …
115Gold standard (test) — For other uses, see Gold standard (disambiguation). In medicine and statistics, gold standard test refers to a diagnostic test or benchmark that is the best available under reasonable conditions. It does not have to be necessarily the best… …
116Electronic health record — This article is about shared or comprehensive computerized health care records in enterprise wide systems. For local computerized records in a specific health care organization, see Electronic medical record. Sample view of an electronic health… …
117Robust regression — In robust statistics, robust regression is a form of regression analysis designed to circumvent some limitations of traditional parametric and non parametric methods. Regression analysis seeks to find the effect of one or more independent… …
118Randomized block design — In the statistical theory of the design of experiments, blocking is the arranging of experimental units in groups (blocks) that are similar to one another. Typically, a blocking factor is a source of variability that is not of primary interest to …
119Chi-squared test — Chi square test is often shorthand for Pearson s chi square test. A chi square test, also referred to as chi squared test or χ2 test, is any statistical hypothesis test in which the sampling distribution of the test statistic is a chi square… …
120Life-cycle assessment — Cradle to grave redirects here. For other uses, see Cradle to the Grave (disambiguation). A life cycle assessment (LCA, also known as life cycle analysis, ecobalance, and cradle to grave analysis)[1] is a technique to assess environmental impacts …
