| least squares | A principle of estimation invented by Gauss in which the estimates of a set of parameters in a statistical model are the quantities that minimise the sum of squared differences between the observed values of the dependent variable and the values predicted by the model.

| least-squares analysis | A principle of estimation in which the estimates of a set of parameters in a statistical model are those quantities minimizing the sum of squared differences between the observed values of a dependent variable and the values predicted by the model. (12 Dec 1998) |
| estimator | A prescription for obtaining an estimate from a random sample of data. An estimator is a procedure, not a result, and therefore is a random variable and has a variance. For instance an estimator of the mean weight in adult men may consist of the prescription "Add up the weights of 100 men and divide by 100." The actual outcome (the estimate) will vary from sample to sample, but one answer will not be a random variable. Least squares estimator, the prescription "Assign to the unknown parameter the value that minimises the mean of the squares of the residual errors". Maximum likelihood estimator, the prescription "Assign to the unknown parameter that value that maximises the likelihood for the sample". For many problems this procedure is an optimal one.

| pelvic plane of least dimensions | The plane that extends from the end of the sacrum to the inferior border of the pubic symphysis; it is bounded posteriorly by the end of the sacrum, laterally by the ischial spines, and anteriorly by the inferior border of the pubic symphysis. Synonym: midplane, plane of least pelvic dimensions, plane of midpelvis, third parallel pelvic plane. (05 Mar 2000) |

| least | Origin: OE. Last, lest, AS. Lsast, lsest, superl. Of lssa less. See Less] Smallest, either in size or degree; shortest; lowest; most unimportant; as, the least insect; the least mercy; the least space. Least is often used with the, as if a noun. "I am the least of the apostles." (1 Cor. Xv. 9) at least, or At the least, at the least estimate, consideration, chance, etc.; hence, at any rate; at all events; even. See However. "He who tempts, though in vain, at least asperses The tempted with dishonor." (Milton) "Upon the mast they saw a young man, at least if he were a man, who sat as on horseback." (Sir P. Sidney) In least, or In the least, in the least degree, manner, etc. "He that is unjust in the least is unjust also in much." . <mathematics> Least squares, a method of deducing from a number of carefully made yet slightly discordant observations of a phenomenon the most probable values of the unknown quantities. It takes as its fundamental principle that the most probable values are those which make the sum of the squares of the residual errors of the observation a minimum.

| least cost planning | (integrated resource planning) A method of power planning that recognises load uncertainty, embodies an emphasis on risk management, and reviews all available and reliable resources to meet future loads. It takes into consideration all costs of a resource, including capital, labour, fuel, maintenance, decommissioning, known environmental impacts, and the difficulty in quantifying the consequences of selecting one resource over another. Least cost planning seeks to minimise total energy costs. (05 Dec 1998) |
| least diffusion circle | In the configuration of rays emerging from a spherocylindrical lens system, the place where diverging rays of the lens first forming a line image are balanced by converging rays of the second lens. (05 Mar 2000) |
