Support of a random variable

    https://www.statlect.com/glossary/support-of-a-random-variable
    For continuous random variables, it is the set of all numbers whose probability density is strictly positive. Example If a continuous random variable has probability density function then its support is. Support of random vectors and random matrices. The same definition applies to random vectors. ...

Probability density function - Wikipedia

    https://en.wikipedia.org/wiki/Probability_density_function
    In probability theory, a probability density function (PDF), or density of a continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the random variable would equal that sample.

density function R Documentation

    https://www.rdocumentation.org/packages/stats/versions/3.6.2/topics/density
    Details. The algorithm used in density.default disperses the mass of the empirical distribution function over a regular grid of at least 512 points and then uses the fast Fourier transform to convolve this approximation with a discretized version of the kernel and then uses linear approximation to evaluate the density at the specified points. ...

    The probability density function ("p.d.f. ") of a continuous random variable X with support S is an integrable function f(x) satisfying the following: (1) f(x) is positive everywhere in the support S, that is, f(x) > …

Using the probability density function (PDF) - Minitab

    The probability density function (PDF) is an equation that represents the probability distribution of a continuous random variable. For example, a machine that cuts corks for wine bottles produces corks with different diameters. In the following bar chart of cork diameters, each bar represents the percent of corks with that corresponding diameter.

    Probability Density Function The probability density function of a random variable must be positive, and the integral value must be equal to 1 for it to be a legitimate function.
