  2. Sample size determination - Wikipedia

    en.wikipedia.org/wiki/Sample_size_determination

    The table shown on the right can be used in a two-sample t-test to estimate the sample sizes of an experimental group and a control group that are of equal size, that is, the total number of individuals in the trial is twice that of the number given, and the desired significance level is 0.05. [4]

  3. Normal distribution - Wikipedia

    en.wikipedia.org/wiki/Normal_distribution

    Conversely, if ⁠ ⁠ is a normal deviate with parameters ⁠ ⁠ and , then this ⁠ ⁠ distribution can be re-scaled and shifted via the formula = / to convert it to the standard normal distribution.

  4. 70/20/10 model (learning and development) - Wikipedia

    en.wikipedia.org/wiki/70/20/10_Model_(Learning...

    This Model was created by Morgan McCall, Michael M. Lombardo, and Robert A. Eichinger by expressing their rationale behind the 70:20:10 model in the following way in The Career Architect Development Planner: [1] Development generally begins with a realization of current or future need and the motivation to do something about it.

  5. Kelly criterion - Wikipedia

    en.wikipedia.org/wiki/Kelly_criterion

    Example of the optimal Kelly betting fraction, versus expected return of other fractional bets. In probability theory, the Kelly criterion (or Kelly strategy or Kelly bet) is a formula for sizing a sequence of bets by maximizing the long-term expected value of the logarithm of wealth, which is equivalent to maximizing the long-term expected geometric growth rate.

  6. Tseytin transformation - Wikipedia

    en.wikipedia.org/wiki/Tseytin_transformation

    The naive approach is to write the circuit as a Boolean expression, and use De Morgan's law and the distributive property to convert it to CNF. However, this can result in an exponential increase in equation size. The Tseytin transformation outputs a formula whose size grows linearly relative to the input circuit's.

  7. Price equation - Wikipedia

    en.wikipedia.org/wiki/Price_equation

    Example for a trait under positive selection. The Price equation shows that a change in the average amount of a trait in a population from one generation to the next is determined by the covariance between the amounts of the trait for subpopulation and the fitnesses of the subpopulations, together with the expected change in the amount of the trait value due to fitness, namely ():

  8. RiskMetrics - Wikipedia

    en.wikipedia.org/wiki/RiskMetrics

    The giant firm J. P. Morgan put the entire world at risk by introducing in the nineties RiskMetrics, a phony method aiming at managing people’s risks. A related method called “ Value-at-Risk ,” which relies on the quantitative measurement of risk, has been spreading.

  9. Laws of Form - Wikipedia

    en.wikipedia.org/wiki/Laws_of_Form

    LoF (T14–15) proves the primary algebra analog of the well-known Boolean algebra theorem that every formula has a normal form. Let A be a subformula of some formula B. When paired with C3, J1a can be viewed as the closure condition for calculations: B is a tautology if and only if A and (A) both appear in depth 0 of B.
