  2. Extraordinary assumptions and hypothetical conditions

    en.wikipedia.org/wiki/Extraordinary_assumptions...

    The distinction between the two lies in the potential veracity of the assumption. A hypothetical condition assumes a condition which is known to be contrary to fact whereas an extraordinary assumption assumes a condition or a fact which is merely unknown or uncertain. The results of an analysis involving any hypothetical conditions are known to ...

  3. Fact table - Wikipedia

    en.wikipedia.org/wiki/Fact_table

    Example of a star schema; the central table is the fact table. In data warehousing, a fact table consists of the measurements, metrics or facts of a business process. It is located at the center of a star schema or a snowflake schema surrounded by dimension tables. Where multiple fact tables are used, these are arranged as a fact constellation ...

  4. Working hypothesis - Wikipedia

    en.wikipedia.org/wiki/Working_hypothesis

    For Putnam, the working hypothesis represents a practical starting point in the design of an empirical research exploration. A contrasting example of this conception of the working hypothesis is illustrated by the brain-in-a-vat thought experiment. This experiment involves confronting the global skeptic position that we, in fact, are all just ...

  5. Statistical hypothesis test - Wikipedia

    en.wikipedia.org/wiki/Statistical_hypothesis_test

    Statistical hypothesis testing is a key technique of both frequentist inference and Bayesian inference, although the two types of inference have notable differences. Statistical hypothesis tests define a procedure that controls (fixes) the probability of incorrectly deciding that a default position (null hypothesis) is incorrect. The procedure ...

  6. Statistical proof - Wikipedia

    en.wikipedia.org/wiki/Statistical_proof

    Bayesian statistics are based on a different philosophical approach for proof of inference.The mathematical formula for Bayes's theorem is: [|] = [|] [] []The formula is read as the probability of the parameter (or hypothesis =h, as used in the notation on axioms) “given” the data (or empirical observation), where the horizontal bar refers to "given".

  7. Post–earnings-announcement drift - Wikipedia

    en.wikipedia.org/wiki/Post–earnings...

    The first component is a positive autocorrelation between seasonal difference (i.e., seasonal random walk forecast errors – the difference between the actual returns and forecasted returns) that is strongest for adjacent quarters, being positive over the first three lag quarters. Second, there is a negative auto correlation between seasonal ...

  8. Analysis of competing hypotheses - Wikipedia

    en.wikipedia.org/wiki/Analysis_of_competing...

    ACH misconceives the nature of the relationship between items of evidence and hypotheses by supposing that items of evidence are, on their own, consistent or inconsistent with hypotheses. ACH treats the hypothesis set as "flat", i.e. a mere list, and so is unable to relate evidence to hypotheses at the appropriate levels of abstraction

  9. Accounting constraints - Wikipedia

    en.wikipedia.org/wiki/Accounting_constraints

    Accounting constraints (also known as the constraints of accounting) are the practical limitations and guidelines that influence how financial statements are prepared and interpreted. These constraints acknowledge that ideal accounting practices may need to be adjusted due to factors like the availability of reliable information, the cost of ...
