Hypothesis, английский
- A suggested explanation for an observation or experimental result, which is then refined or disproved by further investigation
- Гипотеза
- N гипотеза critical period ~ гипотеза критического периода linguistic relativity ~ гипотеза лингвистиче- ской относительности (син. sapir–whorf ~) localist ~ локалистская гипотеза3 nostratic ~ ностратическая гипотеза sapir–whorf ~ гипотеза сепира–уорфа (син. linguistic relativity ~) single segment ~ гипотеза единого сегмента
- Гипотеза. положение, которое предположительно отражает истину или которое используется как основа для аргументации того, что еще не доказано.
- Гипотеза; предположение; допущение hypothesis-driven управляемый гипотезами
- Гипотеза, предположение
- An assertion, proposition or statement about relations or constraints whose truth-value is as of yet unknown .but in principle determinable by tests involving generally empirical but also logical evidence. hypotheses are generally derived from theories or models and when these theories have some validity of their own, they consititute predictions. l&qh
Approximating, английский
Приближающий; аппроксимирующий
Probability, английский
- Probability can be generally defined as a measure of how likely some event will occur. the event could be an explosion, a lottery win or perhaps cancer induction. mathematically speaking, the value of probability varies between 0 and 1 where 0 means an ev
- Вероятность. возможность.
- The probability of an event is a number between zero and 100%. the meaning (interpretation) of probability is the subject of theories of probability, which differ in their interpretations. however, any rule for assigning probabilities to events has to satisfy the axioms of probability.
- Вероятность
- Вероятность probability sample, syn. random sample
- Вероятность. мера случайности появления конкретного события. например, вероятность случайного выбора из популяции человека с конкретным качеством соответствует доле людей в популяции, обладающих этим качеством.
- Вероятность; возможность
- Вероятность; обеспеченность (гидрологической величины) ~ of no-failure вероятность безотказной работы
- Probability is a method for representing uncertainty about propositions or events. it represents the uncertainty about a proposition on a scale from 0 to 1, with a 0 representing complete certainty that the proposition is false or an event will not occur and a value of one will represent the opposite. formally, a probability measure is one that follows kolmogorov`s axioms. there are two main schools of thought on the meaning of probability. frequentists take a narrow interpretation of probability allowing only hypothetically repeatable events or experiments as being quantifiable by probability, while bayesians take a broader interpretation that allows reasoning about "one-shot" events and propositions based on the current knowledge about nature. the bayesian interpretation is most commonly used in artificial intelligence, while the frequentist interpretation is most commonly taught in statistics courses. the label "bayesian" arises from the central role that the bayes theorem plays in this use of probability. it allows one to reason from effects to causes and encourages the use of probability measures to describe supposedly fixed events or propositions which frequentists disallow. the probability for these events reflects one`s state of knowledge about the event, rather than being an assertion that the unknown event can vary. for example, a bayesian would have no qualms about making statements about the probability that a given die, rolled and hidden from his sight is, for example, a six. a frequentist would be unable to make such a statement, preferring to talk about his confidence in the method when applied to a hypothetically large number of repeated experiments. in the end, they would act in similar ways. when the long run data are available, bayesians and frequentists end up with the same estimates. see also: bayes theorem, kolmogorov`s axioms.
- Вероятность. математическое измерение возможности появления неко-его события, выраженное в виде дроби или процента [30]. значения статистической вероятности лежат в пределах от 1 или 100 процентов (всегда) до 0 или 0 процентов (никогда) [20]. наибольшее приближение к истинной вероятности дает относитель-ная частота события, полученная на основе большой серии измерений или результа-тов [33]. вероятность может быть также определена как выражение в некоторой неопределимой форме "степени уверенности" или как предельная частота события в бесконечной случайной последовательности [49].
- The likelihood of something happening. for example, sale being made.

- The relative likelihood of a particular outcome among all possible outcomes.
- Likelihood that an event may occur, expressed as a number between 0 and 1.

Invalid (logical) argument., английский
An invalid logical argument is one in which the truth of the premises does not guarantee the truth of the conclusion. for example, the following logical argument is invalid: if the forecast calls for rain, i will not wear sandals. the forecast does not ca
Controlled experiment., английский
An experiment that uses the method of comparison to evaluate the effect of a treatment by comparing treated subjects with a control group, who do not receive the treatment.
