  2. Primes in arithmetic progression - Wikipedia

    en.wikipedia.org/wiki/Primes_in_arithmetic...

    This CPAP-10 has the smallest possible common difference, 7# = 210. The only other known CPAP-10 as of 2018 was found by the same people in 2008. If a CPAP-11 exists then it must have a common difference which is a multiple of 11# = 2310. The difference between the first and last of the 11 primes would therefore be a multiple of 23100.

  3. Arithmetic progression - Wikipedia

    en.wikipedia.org/wiki/Arithmetic_progression

    The product of the members of a finite arithmetic progression with an initial element a 1, common differences d, and n elements in total is determined in a closed expression a 1 a 2 a 3 ⋯ a n = a 1 ( a 1 + d ) ( a 1 + 2 d ) . . .

  4. Module:Template test case - Wikipedia

    en.wikipedia.org/wiki/Module:Template_test_case

    This module provides a framework for making templates which produce a template test case.While test cases can be made manually, using Lua-based templates such as the ones provided by this module has the advantage that the template arguments only need to be input once, thus reducing the effort involved in making test cases and reducing the possibility of errors in the input.

  5. Just-noticeable difference - Wikipedia

    en.wikipedia.org/wiki/Just-noticeable_difference

    The JND formula has an objective interpretation (implied at the start of this entry) as the disparity between levels of the presented stimulus that is detected on 50% of occasions by a particular observed response, [3] rather than what is subjectively "noticed" or as a difference in magnitudes of consciously experienced 'sensations'.

  6. Pooled variance - Wikipedia

    en.wikipedia.org/wiki/Pooled_variance

    The pooled variance is an estimate of the fixed common variance underlying various populations that have different means. We are given a set of sample variances s i 2 {\displaystyle s_{i}^{2}} , where the populations are indexed i = 1 , … , m {\displaystyle i=1,\ldots ,m} ,

  8. Geometric progression - Wikipedia

    en.wikipedia.org/wiki/Geometric_progression

    A geometric progression, also known as a geometric sequence, is a mathematical sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed number called the common ratio. For example, the sequence 2, 6, 18, 54, ... is a geometric progression with a common ratio of 3.

  9. Strictly standardized mean difference - Wikipedia

    en.wikipedia.org/wiki/Strictly_standardized_mean...

    For quality control, one index for the quality of an HTS assay is the magnitude of difference between a positive control and a negative reference in an assay plate. For hit selection, the size of effects of a compound (i.e., a small molecule or an siRNA) is represented by the magnitude of difference between the compound and a negative reference ...
