  2. Optical storage media writing and reading speed - Wikipedia

    en.wikipedia.org/wiki/Optical_storage_media...

    Resources available to the program: Reading or writing data on a disc consumes moderate to high level of system resources (including memory and CPU resources), and running other programs at the same time may force the CD/DVD drive to choose a lower speed automatically, to accommodate the available resources.

  3. Estimator - Wikipedia

    en.wikipedia.org/wiki/Estimator

    In statistics, an estimator is a rule for calculating an estimate of a given quantity based on observed data: thus the rule (the estimator), the quantity of interest (the estimand) and its result (the estimate) are distinguished. [1] For example, the sample mean is a commonly used estimator of the population mean. There are point and interval ...

  4. Raygor readability estimate - Wikipedia

    en.wikipedia.org/wiki/Raygor_Readability_Estimate

    The Raygor estimate graph is a readability metric for English text. It was developed by Alton L. Raygor, who published it in 1977. [1] The US grade level is calculated by the average number of sentences and letters per hundred words. These averages are plotted onto a specific graph where the intersection of the average number of sentences and ...

  5. Spectral density estimation - Wikipedia

    en.wikipedia.org/wiki/Spectral_density_estimation

    In statistical signal processing, the goal of spectral density estimation (SDE) or simply spectral estimation is to estimate the spectral density (also known as the power spectral density) of a signal from a sequence of time samples of the signal. [1] Intuitively speaking, the spectral density characterizes the frequency content of the signal.

  6. Allan variance - Wikipedia

    en.wikipedia.org/wiki/Allan_variance

    The B 3 bias function is useful to adjust non-overlapping and overlapping variable τ estimator values based on dead-time measurements of observation time τ 0 and time between observations T 0 to normal dead-time estimates. The bias function becomes after analysis (for the N = 2 case)

  7. Flesch–Kincaid readability tests - Wikipedia

    en.wikipedia.org/wiki/Flesch–Kincaid...

    "The Flesch–Kincaid" (F–K) reading grade level was developed under contract to the U.S. Navy in 1975 by J. Peter Kincaid and his team. [1] Related U.S. Navy research directed by Kincaid delved into high-tech education (for example, the electronic authoring and delivery of technical information), [2] usefulness of the Flesch–Kincaid readability formula, [3] computer aids for editing tests ...

  8. Fry readability formula - Wikipedia

    en.wikipedia.org/wiki/Fry_readability_formula

    A rendition of the Fry graph. The Fry readability formula (or Fry readability graph) is a readability metric for English texts, developed by Edward Fry. [1]The grade reading level (or reading difficulty level) is calculated by the average number of sentences (y-axis) and syllables (x-axis) per hundred words.

  9. Dyschronometria - Wikipedia

    en.wikipedia.org/wiki/Dyschronometria

    Dyschronometria, also called dyschronia, is a condition of cerebellar dysfunction in which an individual cannot accurately estimate the amount of time that has passed (i.e., distorted time perception). It is associated with cerebellar ataxia, [1] [2] when the cerebellum has been damaged and does not function to its fullest ability.
