  2. Simulation hypothesis - Wikipedia

    en.wikipedia.org/wiki/Simulation_hypothesis

    The simulation hypothesis proposes that what one experiences as the world is actually a simulated reality, such as a computer simulation in which we ourselves are constructs. [ 1 ] [ 2 ] There has been much debate over this topic in the philosophical discourse, and regarding practical applications in computing .

  3. Verification and validation of computer simulation models

    en.wikipedia.org/wiki/Verification_and...

    The hypothesis to be tested is if D is within the acceptable range of accuracy. Let L = the lower limit for accuracy and U = upper limit for accuracy. Then H 0 L ≤ D ≤ U. versus H 1 D < L or D > U. is to be tested. The operating characteristic (OC) curve is the probability that the null hypothesis is accepted when it is true.

  4. Power (statistics) - Wikipedia

    en.wikipedia.org/wiki/Power_(statistics)

    We define two hypotheses the null hypothesis, and the alternative hypothesis. If we design the test such that α is the significance level - being the probability of rejecting H 0 {\displaystyle H_{0}} when H 0 {\displaystyle H_{0}} is in fact true, then the power of the test is 1 - β where β is the probability of failing to reject H 0 ...

  5. Bayesian inference - Wikipedia

    en.wikipedia.org/wiki/Bayesian_inference

    Bayesian inference (/ ˈ b eɪ z i ə n / BAY-zee-ən or / ˈ b eɪ ʒ ən / BAY-zhən) [1] is a method of statistical inference in which Bayes' theorem is used to calculate a probability of a hypothesis, given prior evidence, and update it as more information becomes available.

    This is an accepted version of this page This is the latest accepted revision, reviewed on 8 February 2025. Discrepancy of the lack of evidence for alien life despite its apparent likelihood This article is about the absence of clear evidence of extraterrestrial life. For a type of estimation problem, see Fermi problem. Enrico Fermi (Los Alamos 1945) The Fermi paradox is the discrepancy ...

  7. Family-wise error rate - Wikipedia

    en.wikipedia.org/wiki/Family-wise_error_rate

    Using a statistical test, we reject the null hypothesis if the test is declared significant. We do not reject the null hypothesis if the test is non-significant. Summing each type of outcome over all H i yields the following random variables:

  8. Tukey's range test - Wikipedia

    en.wikipedia.org/wiki/Tukey's_range_test

    Since the null hypothesis for Tukey's test states that all means being compared are from the same population (i.e. μ 1 = μ 2 = μ 3 = ... = μ k), the means should be normally distributed (according to the central limit theorem) with the same model standard deviation σ, estimated by the merged standard error, , for all the samples; its ...

  9. Wilks' theorem - Wikipedia

    en.wikipedia.org/wiki/Wilks'_theorem

    The hypothesis space H is constrained by the usual constraints on a probability distribution, , and + =. The space of the null hypothesis H 0 {\displaystyle H_{0}} is the subspace where p 1 j = p 2 j {\displaystyle p_{1j}=p_{2j}} .
