1) varak; 2) pištaneš; 3) varak dâdan
Fr.: 1, 2) biais; 3) biaiser
Leaning of the mind toward or away from something; especially:
a personal and sometimes unreasoned judgment.
From M.Fr. biais "slant," perhaps ultimately from Gk. epikarsios "slanting, oblique," from epi- "upon" + karsios "oblique."
Varak, from var "side, direction"
+ -ak suffix denoting relation, affinity, similarity
(as in dastak, poštak, pašmak, xarak,
nâxonak, mušak, eynak).
Note also var in yekvar "slanting, inclined".
irang-e varak, xatâ-ye ~
Fr.: erreur de biais
A measurement error that remains constant in magnitude for all observations; for example an incorrectly set zero adjustment.
nurdâd barây-e varak
Fr.: pose pour biais
CCD frame with exposure time set to zero and giving the bias level.
In → CCD detectors, same as → bias and → offset.
Fr.: voltage de biais
A voltage applied or developed between two electrodes as a bias.
Marked by or exhibiting bias; characterized by settled and often prejudiced outlook.
Biased, from → bias + adj. suffix -ed.
Varakdâr, from varak, → bias + -dâr "possessing, having," from dâštan "to possess, to have."
Fr.: estimation biasiée
Of a population parameter, if the mean or expectation of the statistics is not equal to the parameter.
biased galaxy formation
diseš-e varakdâr-e kahkašânhâ
Fr.: formation biaisée de galaxies
The theory that bright galaxies form preferentially from anomalously overdense perturbations in the → early Universe.
Fr.: échantillon biaisé
A sample that is not a true representative of a → statistical population to which generalizations are to be made. A sample which is not → randomly constituted.
Fr.: statistique biasée
A statistics based on a → biased sample.
→ biased; → statistics.
Fr.: soustraire le biais
To substract the → bias from a flat-field or science frame obtained using an electronic detector.
Varak zodudan, from varak→ bias + zodudan "to polish, clean," Mid.Pers. uzdātan, Av. uzdā-, from uz-, → ex-, + dā- "make, create."
Fr.: soustraction du biais
The process of removing the → bias from a → flat-field or science → frame. → debias
Verbal noun of → debias.
Fr.: biais cinématique
A systematic error introduced in a sample of stellar → proper motion data by higher velocity stars that are easier to measure.
Fr.: biais de Lutz-Kelker
A systematic error that can be introduced when → trigonometric parallaxes are used to calibrate a luminosity system. The bias arises when stars are selected by a lower limit in the observed parallax values. This favors the stars for which the measured parallax result is relatively too large.
Named after Th. Lutz & D.H. E. Kelker, 1973, PASP 85, 573; → bias.
Fr.: biais de Malmquist
A selection effect in observational astronomy. If a sample of objects (galaxies, quasars, stars, etc.) is flux-limited, then the observer will see an increase in average luminosity with distance, because the less luminous sources at large distances will not be detected.
Named after the Swedish astronomer Gunnar Malmquist (1893-1982); → bias.
Fr.: biais observationnel
An error in observation arising from systematically favoring brighter or weaker objects or some particular object morphologies; e.g. → Malmquist bias.
→ observational; → bias.
Fr.: biais de l'échantillonnage
That part of the difference between the expected value of the sample estimator and the true value of the characteristic which results from the sampling procedure, the estimating procedure, or their combination.
Fr.: non biaisé
Not biased or prejudiced.
→ un- + →
Bi- "without" + varak, → bias.
Fr.: estimateur non biaisé
A sample statistics when the mean of the sampling distribution of that statistic can be shown to be equal to the parameter being estimated.
nemunân-e a bi-varak
Fr.: échantillon non biaisé
A sample in which every individual element in the population has an equal chance of being selected.
