  2. Therapeutic index - Wikipedia

    en.wikipedia.org/wiki/Therapeutic_index

    For example, the risk associated with benzodiazepines increases significantly when taken with alcohol, [18] [19] [20] depressants, [18] opiates, [19] [21] [22] [20] [23] or stimulants [24] when compared with being taken alone. Therapeutic index also does not take into account the ease or difficulty of reaching a toxic or lethal dose.

  3. Process window index - Wikipedia

    For example, a thermal profile with three thermocouples, with four profile statistics logged for each thermocouple, would have a set of twelve statistics for that thermal profile. In this case, the PWI would be the highest value among the twelve percentages of the respective process windows. The formula to calculate PWI is: [7] = = …

    Formula Value Absolute risk increase ARI EER − CER: 0.1, or 10% Number needed to harm: NNH 1 / (EER − CER) 10 Relative risk (risk ratio) RR EER / CER: 1.25 Relative risk increase RRI (EER − CER) / CER, or RR − 1 0.25, or 25% Attributable fraction among the exposed: AF e (EER − CER) / EER: 0.2 Odds ratio: OR (EE / EN) / (CE / CN) 1.5

    The true-positive rate is also known as sensitivity or probability of detection. [1] The false-positive rate is also known as the probability of false alarm [1] and equals (1 − specificity). The ROC is also known as a relative operating characteristic curve, because it is a comparison of two operating characteristics (TPR and FPR) as the ...

    However, this effectively simplifies to a much simpler formula: = = | | = | | Confusingly, sometimes when people refer to wMAPE they are talking about a different model in which the numerator and denominator of the wMAPE formula above are weighted again by another set of custom weights w i {\displaystyle w_{i}} .

  8. Beneish M-score - Wikipedia

    The threshold value is -1.78 for the model whose coefficients are reported above. (see Beneish 1999, Beneish, Lee, and Nichols 2013, and Beneish and Vorst 2020). If M-score is less than -1.78, the company is unlikely to be a manipulator. For example, an M-score value of -2.50 suggests a low likelihood of manipulation.

  9. Tax bracket - Wikipedia

    en.wikipedia.org/wiki/Tax_bracket

    Imagine that there are three tax brackets: 10%, 20%, and 30%. The 10% rate applies to income from $1 to $10,000; the 20% rate applies to income from $10,001 to $20,000; and the 30% rate applies to all income above $20,000. Under this system, someone earning $10,000 is taxed at 10%, paying a total of $1,000. Someone earning $5,000 pays $500, and ...
