Noun
density function (plural density functions)
(probability theory) Clipping of probability density function.
A common predictive distribution over future samples is the so-called plug-in distribution, formed by plugging a suitable estimate for the rate parameter λ into the exponential density function. Source: Internet
The density function of this distribution can be written as : The delta function is also used in a completely different way to represent the local time of a diffusion process (like Brownian motion ). Source: Internet
Histograms give a rough sense of the density of the underlying distribution of the data, and often for density estimation : estimating the probability density function of the underlying variable. Source: Internet
In practice this may be difficult to estimate as the density function is usually unknown. Source: Internet
Integration of the normal probability density function of the velocity, above, over the course (from 0 to ) and path angle (from 0 to ), with substitution of the speed for the sum of the squares of the vector components, yields the speed distribution. Source: Internet
In this case, the probability density function or probability mass function will be a special case of the more general form : where is the location parameter, θ represents additional parameters, and is a function parametrized on the additional parameters. Source: Internet
