  2. Big O notation - Wikipedia

    en.wikipedia.org/wiki/Big_O_notation

    Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. Big O is a member of a family of notations invented by German mathematicians Paul Bachmann, [1] Edmund Landau, [2] and others, collectively called Bachmann–Landau notation or asymptotic notation.

  3. Parts-per notation - Wikipedia

    en.wikipedia.org/wiki/Parts-per_notation

    In science and engineering, the parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement .

  4. Omega - Wikipedia

    en.wikipedia.org/wiki/Omega

    In statistics, it is used as the symbol for the sample space, or total set of possible outcomes. In triangle geometry, Brocard points; In number theory, Ω is the number of prime divisors of n (counting multiplicity). [8] In notation related to Big O notation to describe the asymptotic behavior of functions. Chaitin's constant.

  5. Exponentiation - Wikipedia

    en.wikipedia.org/wiki/Exponentiation

    In the base ten number system, integer powers of 10 are written as the digit 1 followed or preceded by a number of zeroes determined by the sign and magnitude of the exponent. For example, 10 3 = 1000 and 10 −4 = 0.0001. Exponentiation with base 10 is used in scientific notation to denote large or small numbers.

  6. Standard normal table - Wikipedia

    en.wikipedia.org/wiki/Standard_normal_table

    Cumulative from mean gives a probability that a statistic is between 0 (mean) and Z. Example: Prob(0 ≤ Z ≤ 0.69) = 0.2549. Cumulative gives a probability that a statistic is less than Z. This equates to the area of the distribution below Z. Example: Prob(Z ≤ 0.69) = 0.7549. Complementary cumulative

  7. IEEE 754 - Wikipedia

    en.wikipedia.org/wiki/IEEE_754

    Its integer part is the largest exponent shown on the output of a value in scientific notation with one leading digit in the significand before the decimal point (e.g. 1.698·10 38 is near the largest value in binary32, 9.999999·10 96 is the largest value in decimal32).

  8. Decibel - Wikipedia

    en.wikipedia.org/wiki/Decibel

    The base-10 logarithm of the ratio of the two power quantities is the number of bels. The number of decibels is ten times the number of bels (equivalently, a decibel is one-tenth of a bel). P and P 0 must measure the same type of quantity, and have the same units before calculating the ratio. If P = P 0 in the above equation, then L P = 0.

  9. Correlation - Wikipedia

    The four variables have the same mean (7.5), variance (4.12), correlation (0.816) and regression line (= +). However, as can be seen on the plots, the distribution of the variables is very different. However, as can be seen on the plots, the distribution of the variables is very different.
