  2. Multiple comparisons problem - Wikipedia

    en.wikipedia.org/wiki/Multiple_comparisons_problem

    Multiple comparisons arise when a statistical analysis involves multiple simultaneous statistical tests, each of which has a potential to produce a "discovery". A stated confidence level generally applies only to each test considered individually, but often it is desirable to have a confidence level for the whole family of simultaneous tests. [ 4 ]

  3. Pumping lemma for regular languages - Wikipedia

    en.wikipedia.org/wiki/Pumping_lemma_for_regular...

    Let be a regular language. Then there exists an integer depending only on such that every string in of length at least (is called the "pumping length") [4] can be written as = (i.e., can be divided into three substrings), satisfying the following conditions:

  4. Invariant subspace - Wikipedia

    en.wikipedia.org/wiki/Invariant_subspace

    A closed subspace of a Banach space is said to be almost-invariant under an operator () if + for some finite-dimensional subspace ; equivalently, is almost-invariant under if there is a finite-rank operator such that (+), i.e. if is invariant (in the usual sense) under +.

  5. Euler's critical load - Wikipedia

    en.wikipedia.org/wiki/Euler's_critical_load

    The cross-section of the column is uniform throughout its length. The direct stress is very small as compared to the bending stress (the material is compressed only within the elastic range of strains). The length of the column is very large as compared to the cross-sectional dimensions of the column. The column fails only by buckling.

  6. Wikipedia:Lua string functions - Wikipedia

    en.wikipedia.org/wiki/Wikipedia:Lua_string_functions

    The string-search functions in Lua script can run extremely fast, comparing millions of characters per second. For example, a search of a 40,000-character article text, for 99 separate words (passed as 99 parameters in a template), ran within one second of Lua CPU clock time.

  7. Multiple Sleep Latency Test - Wikipedia

    en.wikipedia.org/wiki/Multiple_Sleep_Latency_Test

    The test consists of four or five 20-minute nap opportunities set two hours apart, often following an overnight sleep study. During the test, data such as the patient's brain waves, EEG, muscle activity, and eye movements are monitored and recorded. The entire test normally takes about 7 hours during the course of a day.
