| 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.

| likelihood | 1. Appearance; show; sign; expression. "What of his heart perceive you in his face By any likelihood he showed to-day ?" (Shak) 2. Likeness; resemblance. "There is no likelihood between pure light and black darkness, or between righteousness and reprobation." (Sir W. Raleigh) 3. Appearance of truth or reality; probability; verisimilitude. Origin: Likely + -hood. Source: Websters Dictionary (01 Mar 1998) |
| likelihood functions | Functions constructed from a statistical model and a set of observed data which give the probability of that data for various values of the unknown model parameters. Those parameter values that maximise the probability are the maximum likelihood estimates of the parameters. (12 Dec 1998) |
| maximum | 1. The greatest possible or actual effect or quantity. 2. The acme of a disease or process. (18 Nov 1997) |
| maximum breathing capacity | The volume of air breathed when an individual breathes as deeply and as quickly as possible for a given time (e.g., 15 sec.). Synonym: maximum breathing capacity. (05 Mar 2000) |
| maximum occipital point | The point on the squama of the occipital bone farthest from the glabella. (05 Mar 2000) |
| maximum permissible dose | <radiobiology> Defined by the International Commission on Radiological Protection as the greatest dose of radiation which, in the light of present knowledge, is not expected to cause detectable bodily injury to a person at any time during his lifetime. This dose has been reduced with each Commission report. The MPD is given in terms of acute or chronic exposure of the whole body or of organs, systems, or regions of the body, and differs for persons who are occupationally exposed versus the public at large. (05 Mar 2000) |
| maximum permissible exposure level | The highest level of exposure to a substance, usually noxious, in the environment or during diagnostic and therapeutic procedures, that a body can tolerate without injury. (12 Dec 1998) |
| maximum temperature | In bacteriology, denoting a temperature above which growth will not take place. (05 Mar 2000) |
| maximum urea clearance | The urea clearance when the urine flow exceeds 2 ml/min; normal value is about 75 ml blood/min per 1.73 m2 body surface area. (05 Mar 2000) |
| maximum velocity | The maximum rate of an enzyme-catalyzed reaction that can be achieved by progressively increasing the substrate concentration at a given enzyme concentration; in cases of substrate inhibition, Vmax is an extrapolated value in the absence of such inhibition; Cf.: Michaelis-Menten equation. The maximum initial rate of shortening of a myocardial fibre that can be obtained under zero load; used to evaluate the contractility of the fibre. (05 Mar 2000) |
| maximum voluntary ventilation | The volume of air breathed when an individual breathes as deeply and as quickly as possible for a given time (e.g., 15 sec.). Synonym: maximum breathing capacity. (05 Mar 2000) |
