  2. Frequency (statistics) - Wikipedia

    en.wikipedia.org/wiki/Frequency_(statistics)

    A frequency distribution table is an arrangement of the values that one or more variables take in a sample. Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval, and in this way, the table summarizes the distribution of values in the sample.

  3. Contingency table - Wikipedia

    en.wikipedia.org/wiki/Contingency_table

    In other words, the two variables are not independent. If there is no contingency, it is said that the two variables are independent. The example above is the simplest kind of contingency table, a table in which each variable has only two levels; this is called a 2 × 2 contingency table. In principle, any number of rows and columns may be used.

  5. Marginal distribution - Wikipedia

    en.wikipedia.org/wiki/Marginal_distribution

    However, in trying to calculate the marginal probability P(H = Hit), what is being sought is the probability that H = Hit in the situation in which the particular value of L is unknown and in which the pedestrian ignores the state of the light. In general, a pedestrian can be hit if the lights are red OR if the lights are yellow OR if the ...

  6. Zipf's law - Wikipedia

    en.wikipedia.org/wiki/Zipf's_law

    In the parabolic fractal distribution, the logarithm of the frequency is a quadratic polynomial of the logarithm of the rank. This can markedly improve the fit over a simple power-law relationship. [36] Like fractal dimension, it is possible to calculate Zipf dimension, which is a useful parameter in the analysis of texts. [37]

  7. Multiway data analysis - Wikipedia

    en.wikipedia.org/wiki/Multiway_data_analysis

    Such data might represent the temperature at different locations (two-way data) sampled over different times (leading to three-way data) Four-way data, using the same spreadsheet analogy, can be represented as a file folder full of separate workbooks. Five-way data and six-way data can be represented by similarly higher levels of data aggregation.

  8. k-way merge algorithm - Wikipedia

    en.wikipedia.org/wiki/K-way_merge_algorithm

    In each game, two of the input elements compete. The winner is promoted to the next round. Therefore, we get a binary tree of games. The list is sorted in ascending order, so the winner of a game is the smaller one of both elements. Loser tree. For k-way merging, it is more efficient to only store the loser of each game (see image).

  9. Time and frequency transfer - Wikipedia

    en.wikipedia.org/wiki/Time_and_frequency_transfer

    The two-way satellite time and frequency transfer (TWSTFT) system being used in comparison among some time laboratories uses a satellite for a common link between the laboratories. The Network Time Protocol uses packet-based messages over an IP network. Historically, the telegraphic determination of longitude was an important way to connect two ...
