  3. Ratio estimator - Wikipedia

    en.wikipedia.org/wiki/Ratio_estimator

    The ratio estimator is a statistical estimator for the ratio of means of two random variables. Ratio estimates are biased and corrections must be made when they are used in experimental or survey work. The ratio estimates are asymmetrical and symmetrical tests such as the t test should not be used to generate confidence intervals.

  6. Ratio distribution - Wikipedia

    en.wikipedia.org/wiki/Ratio_distribution

    A ratio distribution (also known as a quotient distribution) is a probability distribution constructed as the distribution of the ratio of random variables having two other known distributions. Given two (usually independent) random variables X and Y, the distribution of the random variable Z that is formed as the ratio Z = X/Y is a ratio ...

  7. Relative strength index - Wikipedia

    en.wikipedia.org/wiki/Relative_strength_index

    A ratio of two averages over the same domain is also always computed as the ratio of two integrals or sums. Yet more specifically, for a real function on an ordered set T {\displaystyle T} (e.g. a price curve), one may consider that function's gradient g {\displaystyle g} , or some weighted variant thereof.

  9. Percentage - Wikipedia

    en.wikipedia.org/wiki/Percentage

    The percent value is computed by multiplying the numeric value of the ratio by 100. For example, to find 50 apples as a percentage of 1,250 apples, one first computes the ratio ⁠ 50 / 1250 ⁠ = 0.04, and then multiplies by 100 to obtain 4%. The percent value can also be found by multiplying first instead of later, so in this example, the 50 ...
