  2. Weighted arithmetic mean - Wikipedia

    en.wikipedia.org/wiki/Weighted_arithmetic_mean

    The weighted arithmetic mean is similar to an ordinary arithmetic mean (the most common type of average), except that instead of each of the data points contributing equally to the final average, some data points contribute more than others.

  3. Expected value - Wikipedia

    en.wikipedia.org/wiki/Expected_value

    Since the probabilities must satisfy p 1 + ⋅⋅⋅ + p k = 1, it is natural to interpret E[X] as a weighted average of the x i values, with weights given by their probabilities p i. In the special case that all possible outcomes are equiprobable (that is, p 1 = ⋅⋅⋅ = p k), the weighted average is given by the standard average. In the ...

  4. Weight function - Wikipedia

    en.wikipedia.org/wiki/Weight_function

    A weight function is a mathematical device used when performing a sum, integral, or average to give some elements more "weight" or influence on the result than other elements in the same set. The result of this application of a weight function is a weighted sum or weighted average.

  5. Price index - Wikipedia

    en.wikipedia.org/wiki/Price_index

    A price index (plural: "price indices" or "price indexes") is a normalized average (typically a weighted average) of price relatives for a given class of goods or services in a given region, during a given interval of time.

  6. Arithmetic mean - Wikipedia

    en.wikipedia.org/wiki/Arithmetic_mean

    A weighted average, or weighted mean, is an average in which some data points count more heavily than others in that they are given more weight in the calculation. [6] For example, the arithmetic mean of 3 {\displaystyle 3} and 5 {\displaystyle 5} is 3 + 5 2 = 4 {\displaystyle {\frac {3+5}{2}}=4} , or equivalently 3 ⋅ 1 2 + 5 ⋅ 1 2 = 4 ...

  7. Economic value added - Wikipedia

    en.wikipedia.org/wiki/Economic_Value_Added

    In accounting, as part of financial statements analysis, economic value added is an estimate of a firm's economic profit, or the value created in excess of the required return of the company's shareholders. EVA is the net profit less the capital charge ($) for raising the firm's capital.

  8. Total factor productivity - Wikipedia

    en.wikipedia.org/wiki/Total_factor_productivity

    TFP is calculated by dividing output by the weighted geometric average of labour and capital input, with the standard weighting of 0.7 for labour and 0.3 for capital. [3] Total factor productivity is a measure of productive efficiency in that it measures how much output can be produced from a certain amount of inputs.

  9. Valuation using multiples - Wikipedia

    en.wikipedia.org/wiki/Valuation_using_multiples

    In economics, valuation using multiples, or "relative valuation", is a process that consists of: identifying comparable assets (the peer group) and obtaining market values for these assets. converting these market values into standardized values relative to a key statistic, since the absolute prices cannot be compared.
