  2. Quantum error correction - Wikipedia

    en.wikipedia.org/wiki/Quantum_error_correction

    Formally, this correcting procedure corresponds to the application of the following map to the output of the channel: = + =. Note that, while this procedure perfectly corrects the output when zero or one flips are introduced by the channel, if more than one qubit is flipped then the output is not properly corrected.

    Note G [a] is a computer algorithm written by Ada Lovelace that was designed to calculate Bernoulli numbers using the hypothetical analytical engine.

    All courses are free to enrol and learn from. The certification exam is optional and comes at a fee of Rs 1000 per course exam. Course credits can also be transferred to other higher education institutions student or the Academic Bank of Credits under the UGC guidelines. NPTEL courses aim for equitable access.

  5. Test statistic - Wikipedia

    en.wikipedia.org/wiki/Test_statistic

    Test statistic is a quantity derived from the sample for statistical hypothesis testing. [1] A hypothesis test is typically specified in terms of a test statistic, considered as a numerical summary of a data-set that reduces the data to one value that can be used to perform the hypothesis test.

  6. Application for employment - Wikipedia

    en.wikipedia.org/wiki/Application_for_employment

    In Spain, the application consists of two parts: the cover letter (Carta de Candidatura) and the CV. No work or training certificates are attached. The cover letter should be short and contain the reason for applying. The CV should be structured in a tabular form. In Spain, multiple job interviews with the same company are common. [citation needed]

  7. Cover letter - Wikipedia

    en.wikipedia.org/wiki/Cover_letter

    Cover letters are typically categorized according to two purposes: applying for a specific, advertised opening ('letter of application') expressing interest in an organization when the job seeker is uncertain whether there are current openings ('letter of inquiry'). [3] According to studies, a good cover letter should: be specific and up-to-date,

  8. Shapiro–Wilk test - Wikipedia

    en.wikipedia.org/wiki/Shapiro–Wilk_test

    The Shapiro–Wilk test tests the null hypothesis that a sample x 1, ..., x n came from a normally distributed population. The test statistic is = (= ()) = (¯), where with parentheses enclosing the subscript index i is the ith order statistic, i.e., the ith-smallest number in the sample (not to be confused with ).

  9. Likelihood-ratio test - Wikipedia

    en.wikipedia.org/wiki/Likelihood-ratio_test

    The likelihood-ratio test, also known as Wilks test, [2] is the oldest of the three classical approaches to hypothesis testing, together with the Lagrange multiplier test and the Wald test. [3] In fact, the latter two can be conceptualized as approximations to the likelihood-ratio test, and are asymptotically equivalent.
