  2. Optimality model - Wikipedia

    en.wikipedia.org/wiki/Optimality_model

    To determine the optimum time spent on a behavior, one can make a graph showing how benefits and costs change with behavior. Optimality is defined as the point where the difference between benefits and costs for a behavior is maximized, which can be done by graphing the benefits and costs on the y-axis and a measure of the behavior on the x-axis.

  3. Optimal foraging theory - Wikipedia

    en.wikipedia.org/wiki/Optimal_foraging_theory

    Using these variables, the optimal diet model can predict how predators choose between two prey types: big prey 1 with energy value E 1 and handling time h 1, and small prey 2 with energy value E 2 and handling time h 2. In order to maximize its overall rate of energy gain, a predator must consider the profitability of the two prey types.

  4. Shelford's law of tolerance - Wikipedia

    en.wikipedia.org/wiki/Shelford's_Law_of_Tolerance

    Shelford's law of tolerance is a principle developed by American zoologist Victor Ernest Shelford in 1911. It states that an organism's success is based on a complex set of conditions and that each organism has a certain minimum, maximum, and optimum environmental factor or combination of factors that determine success. [1]

  5. Marginal value theorem - Wikipedia

    en.wikipedia.org/wiki/Marginal_value_theorem

    These researchers point out that the marginal value theorem is a starting point, but complexity and nuances must be incorporated into models and tests for foraging and patch-use. One other type of model that has been used in place of MVT in predicting foraging behavior is the state-dependent behavior model.

  6. 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]

  7. Optimality theory - Wikipedia

    en.wikipedia.org/wiki/Optimality_Theory

    Optimality theory (frequently abbreviated OT) is a linguistic model proposing that the observed forms of language arise from the optimal satisfaction of conflicting constraints. OT differs from other approaches to phonological analysis, which typically use rules rather than constraints.

  8. Karush–Kuhn–Tucker conditions - Wikipedia

    en.wikipedia.org/wiki/Karush–Kuhn–Tucker...

    Given this definition, each coefficient is the rate at which the value function increases as increases. Thus if each a i {\displaystyle a_{i}} is interpreted as a resource constraint, the coefficients tell you how much increasing a resource will increase the optimum value of our function f {\displaystyle f} .

  9. Arousal - Wikipedia

    en.wikipedia.org/wiki/Arousal

    Arousal is the physiological and psychological state of being awoken or of sense organs stimulated to a point of perception. It involves activation of the ascending reticular activating system (ARAS) in the brain, which mediates wakefulness, the autonomic nervous system, and the endocrine system, leading to increased heart rate and blood pressure and a condition of sensory alertness, desire ...
