  2. Linear interpolation - Wikipedia

    en.wikipedia.org/wiki/Linear_interpolation

    A description of linear interpolation can be found in the ancient Chinese mathematical text called The Nine Chapters on the Mathematical Art (九章算術), [1] dated from 200 BC to AD 100 and the Almagest (2nd century AD) by Ptolemy. The basic operation of linear interpolation between two values is commonly used in computer graphics.

  3. List of open-source software for mathematics - Wikipedia

    en.wikipedia.org/wiki/List_of_open-source...

    A computer algebra system (CAS) is a software product designed for manipulation of mathematical formulae.The principal objective of a computer algebra system is to systematize monotonous and sometimes problematic algebraic manipulation tasks.

  4. Graphical model - Wikipedia

    en.wikipedia.org/wiki/Graphical_model

    Generally, probabilistic graphical models use a graph-based representation as the foundation for encoding a distribution over a multi-dimensional space and a graph that is a compact or factorized representation of a set of independences that hold in the specific distribution.

  5. Scatter plot - Wikipedia

    en.wikipedia.org/wiki/Scatter_plot

    An equation for the correlation between the variables can be determined by established best-fit procedures. For a linear correlation, the best-fit procedure is known as linear regression and is guaranteed to generate a correct solution in a finite time. No universal best-fit procedure is guaranteed to generate a correct solution for arbitrary ...

  6. Linear trend estimation - Wikipedia

    en.wikipedia.org/wiki/Linear_trend_estimation

    Levels of trypsin (ng/mL) rise in a direct linear trend of 128, 152, 194, 207, 215, 218 (data from Altman). Unsurprisingly, a 'standard' ANOVA gives p < 0.0001, whereas linear trend estimation gives p = 0.00006. Incidentally, it could be reasonably argued that as age is a natural continuously variable index, it should not be categorized into ...

  7. Direct linear plot - Wikipedia

    en.wikipedia.org/wiki/Direct_linear_plot

    This is also the case for non-linear plots, such as that of against , often wrongly called a "Michaelis-Menten plot", and that of against ⁡ used by Michaelis and Menten. [6] In contrast to all of these, the direct linear plot is a plot in parameter space , with observations represented by lines rather than as points.

  8. Spline (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Spline_(mathematics)

    The next most simple spline has degree 1. It is also called a linear spline. A closed linear spline (i.e, the first knot and the last are the same) in the plane is just a polygon. A common spline is the natural cubic spline. A cubic spline has degree 3 with continuity C 2, i.e. the values and first and second derivatives are continuous. Natural ...

  9. Diophantine equation - Wikipedia

    en.wikipedia.org/wiki/Diophantine_equation

    This is a linear Diophantine equation, related to Bézout's identity. + = + The smallest nontrivial solution in positive integers is 12 3 + 1 3 = 9 3 + 10 3 = 1729.It was famously given as an evident property of 1729, a taxicab number (also named Hardy–Ramanujan number) by Ramanujan to Hardy while meeting in 1917.
