  2. Data dependency - Wikipedia

    en.wikipedia.org/wiki/Data_dependency

    1. B = 3 2. A = B + 1 3. B = 7 Example: MUL R3,R1,R2 ADD R2,R5,R6 It is clear that there is anti-dependence between these 2 instructions. At first we read R2 then in second instruction we are Writing a new value for it. An anti-dependency is an example of a name dependency. That is, renaming of variables could remove the dependency, as in the ...

  3. Correlation - Wikipedia

    en.wikipedia.org/wiki/Correlation

    The degree of dependence between variables X and Y does not depend on the scale on which the variables are expressed. That is, if we are analyzing the relationship between X and Y, most correlation measures are unaffected by transforming X to a + bX and Y to c + dY, where a, b, c, and d are constants (b and d being positive).

  4. Covariance - Wikipedia

    en.wikipedia.org/wiki/Covariance

    The covariance is sometimes called a measure of "linear dependence" between the two random variables. That does not mean the same thing as in the context of linear algebra (see linear dependence ). When the covariance is normalized, one obtains the Pearson correlation coefficient , which gives the goodness of the fit for the best possible ...

  5. Dependent and independent variables - Wikipedia

    en.wikipedia.org/wiki/Dependent_and_independent...

    In mathematics, a function is a rule for taking an input (in the simplest case, a number or set of numbers) [5] and providing an output (which may also be a number). [5] A symbol that stands for an arbitrary input is called an independent variable, while a symbol that stands for an arbitrary output is called a dependent variable. [6]

  6. Reverse tolerance - Wikipedia

    en.wikipedia.org/wiki/Reverse_tolerance

    Reverse tolerance or drug sensitization is a pharmacological phenomenon describing subjects' increased reaction (positive or negative) to a drug following its repeated use. [4] Not all drugs are subject to reverse tolerance. This is the opposite of drug tolerance, in which the effect or the subject's reaction decreases following its repeated ...

  7. Dependence relation - Wikipedia

    If is a non-empty set with a dependence relation , then always has a basis with respect to . Furthermore, any two bases of X {\displaystyle X} have the same cardinality . If a S {\displaystyle a\triangleleft S} and S ⊆ T {\displaystyle S\subseteq T} , then a T {\displaystyle a\triangleleft T} , using property 3. and 1.

  8. Counterdependency - Wikipedia

    en.wikipedia.org/wiki/Counterdependency

    In similar fashion, the teenager needs to be able to establish the fact of their separate mind to their parents, [6] even if only through a sustained state of cold rejection; [7] and again unresolved adolescent issues can lead to a mechanical counterdependence and unruly assertiveness in later life.

  9. Fourth power - Wikipedia

    en.wikipedia.org/wiki/Fourth_power

    n 4 = n × n × n × n. Fourth powers are also formed by multiplying a number by its cube. Furthermore, they are squares of squares. Some people refer to n 4 as n tesseracted, hypercubed, zenzizenzic, biquadrate or supercubed instead of “to the power of 4”. The sequence of fourth powers of integers, known as biquadrates or tesseractic ...
