Kernel density estimation of 100 normally distributed random numbers using different smoothing bandwidths.. In statistics, kernel density estimation (KDE) is the application of kernel smoothing for probability density estimation, i.e., a non-parametric method to estimate the probability density function of a random variable based on kernels as weights.
The previous figure is a graphical representation of kernel density estimate, which we now define in an exact manner. Let x 1, x 2, ..., x n be a sample of d-variate random vectors drawn from a common distribution described by the density function ƒ.
In 2008, developers of LabPlot and SciDAVis (another Origin clone, forked from QtiPlot) "found their project goals to be very similar" and decided to merge their code into a common backend while maintaining two frontends: LabPlot, integrated with the KDE desktop environment (DE); and SciDAVis, written in DE-independent Qt with fewer dependencies for easier cross-platform use.
KmPlot is a mathematical function plotter for the KDE Desktop bundled with the rest of the KDE Applications. [1] The program is recommended for high school and college use. [ 2 ] KmPlot came bundled with Edubuntu .
KWayland is the KDE library for implementing Wayland support in KDE applications, it fulfills needs beyond what QtWayland provides. All the KDE applications in a plasma-wayland-session use this library and LXQt maybe as well. KWayland has been part of KDE Frameworks since 5.22 (May 2016); it was formerly distributed as part of KDE Plasma 5.
KAlgebra is a mathematical graph calculator included in the KDE education package. [2] While it is based on the MathML content markup language, knowledge of MathML is not required for use. The calculator includes numerical, logical, symbolic, and analytical functions, and can plot the results onto a 2D or 3D graph.
KDE Plasma is a set of graphical shells developed by KDE for Unix-like operating systems. With the KDE brand repositioning in 2009, Plasma 4.4 succeeded KDE 4.3.Currently, it has four workspace variants: one for desktop PCs and laptops (Plasma Desktop) [a], [4] [5] [6] one for TVs (Plasma Bigscreen), [7] one for smartphones (Plasma Mobile), [8] and another for embedded and touch-enabled ...
A KDE Patron is an individual or organization supporting the KDE community by donating at least 5000 Euro (depending on the company's size) to the KDE e.V. [29] As of February 2024, there are nine such patrons: Blue Systems, Canonical Ltd., Google, GnuPG, Kubuntu Focus, Slimbook, SUSE, The Qt Company, and TUXEDO Computers.
