  2. Pairwise summation - Wikipedia

    en.wikipedia.org/wiki/Pairwise_summation

    If the inputs are all non-negative, then the condition number is 1. Note that the ⁡ denominator is effectively 1 in practice, since ⁡ is much smaller than 1 until n becomes of order 2 1/ε, which is roughly 10 10 15 in double precision.

  3. Metabolic equivalent of task - Wikipedia

    en.wikipedia.org/wiki/Metabolic_equivalent_of_task

    The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...

  4. Conditional probability - Wikipedia

    en.wikipedia.org/wiki/Conditional_probability

    For events in B, two conditions must be met: the probability of B is one and the relative magnitudes of the probabilities must be preserved. The former is required by the axioms of probability , and the latter stems from the fact that the new probability measure has to be the analog of P in which the probability of B is one - and every event ...

  5. Condition number - Wikipedia

    en.wikipedia.org/wiki/Condition_number

    Condition numbers can also be defined for nonlinear functions, and can be computed using calculus.The condition number varies with the point; in some cases one can use the maximum (or supremum) condition number over the domain of the function or domain of the question as an overall condition number, while in other cases the condition number at a particular point is of more interest.

  6. Conditional expectation - Wikipedia

    en.wikipedia.org/wiki/Conditional_expectation

    If the random variable can take on only a finite number of values, the "conditions" are that the variable can only take on a subset of those values. More formally, in the case when the random variable is defined over a discrete probability space , the "conditions" are a partition of this probability space.

    if discount < 11% then print (you have to pay $30) elseif discount<21% then print (you have to pay $20) elseif discount<31% then print (you have to pay $10) end if; In the example above, if the discount is 10%, then the first if statement will be evaluated as true and "you have to pay $30" will be printed out.

  8. Running total - Wikipedia

    en.wikipedia.org/wiki/Running_total

    A running total or rolling total is the summation of a sequence of numbers which is updated each time a new number is added to the sequence, by adding the value of the new number to the previous running total. Another term for it is partial sum. The purposes of a running total are twofold.

  9. Maximum subarray problem - Wikipedia

    en.wikipedia.org/wiki/Maximum_subarray_problem

    For example, for the array of values [−2, 1, −3, 4, −1, 2, 1, −5, 4], the contiguous subarray with the largest sum is [4, −1, 2, 1], with sum 6. Some properties of this problem are: If the array contains all non-negative numbers, then the problem is trivial; a maximum subarray is the entire array.
