  2. Condition of average - Wikipedia

    en.wikipedia.org/wiki/Condition_of_average

    Illustration of the partial payout of Sum Insured against probability of occurrence. Condition of average (also called underinsurance [1] in the U.S., or principle of average, [2] subject to average, [3] or pro rata condition of average [4] in Commonwealth countries) is the insurance term used when calculating a payout against a claim where the policy undervalues the sum insured.

  3. Aggregate function - Wikipedia

    en.wikipedia.org/wiki/Aggregate_function

    For example, AVERAGE=SUM/COUNT and RANGE=MAX−MIN. In the MapReduce framework, these steps are known as InitialReduce (value on individual record/singleton set), Combine (binary merge on two aggregations), and FinalReduce (final function on auxiliary values), [ 5 ] and moving decomposable aggregation before the Shuffle phase is known as an ...

  4. Highest averages method - Wikipedia

    en.wikipedia.org/wiki/Highest_averages_method

    A majority-preservation clause guarantees any party winning a majority of the vote will receive at least half the seats in a legislature. [20] Without such a clause, it is possible for a party with slightly more than half the vote to receive just barely less than half the seats (if using a method other than D'Hondt). [20]

  5. List of price index formulas - Wikipedia

    en.wikipedia.org/wiki/List_of_price_index_formulas

    This index uses the arithmetic average of the current and based period quantities for weighting. It is considered a pseudo-superlative formula and is symmetric. [12] The use of the Marshall-Edgeworth index can be problematic in cases such as a comparison of the price level of a large country to a small one.

  6. Ordered weighted averaging - Wikipedia

    en.wikipedia.org/wiki/Ordered_weighted_averaging

    [1] [2] Many notable mean operators such as the max, arithmetic average, median and min, are members of this class. They have been widely used in computational intelligence because of their ability to model linguistically expressed aggregation instructions.

  7. Law of total probability - Wikipedia

    en.wikipedia.org/wiki/Law_of_total_probability

    [citation needed] One author uses the terminology of the "Rule of Average Conditional Probabilities", [4] while another refers to it as the "continuous law of alternatives" in the continuous case. [5] This result is given by Grimmett and Welsh [6] as the partition theorem, a name that they also give to the related law of total expectation.

  8. Aggregation problem - Wikipedia

    en.wikipedia.org/wiki/Aggregation_problem

    A typical example is the aggregate production function. [2] Another famous problem is Sonnenschein-Mantel-Debreu theorem. Most of macroeconomic statements comprise this problem. Examples of aggregates in micro- and macroeconomics relative to less aggregated counterparts are: Food vs. apples; Price level and real GDP vs. the price and quantity ...

  9. Conditional expectation - Wikipedia

    en.wikipedia.org/wiki/Conditional_expectation

    The unconditional expectation of rainfall for an unspecified day is the average of the rainfall amounts for those 3652 days. The conditional expectation of rainfall for an otherwise unspecified day known to be (conditional on being) in the month of March, is the average of daily rainfall over all 310 days of the ten–year period that fall in ...
