  2. Lookup table - Wikipedia

    en.wikipedia.org/wiki/Lookup_table

    When the program requires the sine of a value, it can use the lookup table to retrieve the closest sine value from a memory address, and may also interpolate to the sine of the desired value, instead of calculating by mathematical formula. Lookup tables can thus used by mathematics coprocessors in computer systems.

  3. Conditional probability table - Wikipedia

    en.wikipedia.org/wiki/Conditional_probability_table

    In statistics, the conditional probability table (CPT) is defined for a set of discrete and mutually dependent random variables to display conditional probabilities of a single variable with respect to the others (i.e., the probability of each possible value of one variable if we know the values taken on by the other variables).

  4. Input Field Separators - Wikipedia

    en.wikipedia.org/wiki/Input_Field_Separators

    If IFS has a value other than the default, then sequences of the whitespace characters space and tab are ignored at the beginning and end of the word, as long as the whitespace character is in the value of IFS (an IFS whitespace character). Any character in IFS that is not IFS whitespace, along with any adjacent IFS whitespace characters ...

  5. Iterated function system - Wikipedia

    en.wikipedia.org/wiki/Iterated_function_system

    IFS fractals are more related to set theory than fractal geometry. [1] They were introduced in 1981. IFS fractals, as they are normally called, can be of any number of dimensions, but are commonly computed and drawn in 2D. The fractal is made up of the union of several copies of itself, each copy being transformed by a function (hence "function ...

  6. q-value (statistics) - Wikipedia

    en.wikipedia.org/wiki/Q-value_(statistics)

    The q-value can be interpreted as the false discovery rate (FDR): the proportion of false positives among all positive results. Given a set of test statistics and their associated q-values, rejecting the null hypothesis for all tests whose q-value is less than or equal to some threshold ensures that the expected value of the false discovery rate is .

  7. Integrated Forecast System - Wikipedia

    en.wikipedia.org/wiki/Integrated_Forecast_System

    It comprises a spectral atmospheric model with a terrain-following vertical coordinate system coupled to a 4D-Var data assimilation system.In 1997 the IFS became the first operational forecasting system to use 4D-Var. [2] Both ECMWF and Météo-France use the IFS to make operational weather forecasts, but using a different configuration and resolution (the Météo-France configuration is ...

  8. IFS AB - Wikipedia

    en.wikipedia.org/wiki/IFS_AB

    In 1996, IFS was listed in the Swedish stock exchange and the product was made into a component based one. This was followed with the launch of its web client and its establishment of an RnD center in Colombo. In 2001, IFS introduced Java-based mobile clients and Internet portals. In 2004, NEC acquired a 7.7% of IFS share capital. By 2005, IFS ...

  9. Standard normal table - Wikipedia

    Example: To find 0.69, one would look down the rows to find 0.6 and then across the columns to 0.09 which would yield a probability of 0.25490 for a cumulative from mean table or 0.75490 from a cumulative table. To find a negative value such as -0.83, one could use a cumulative table for negative z-values [3] which yield a probability of 0.20327.
