density_at

Density Probability at a Given Value

Description

Compute the density value at a given point of a distribution (i.e., the value of the y axis of a value x of a distribution).

Usage

density_at(posterior, x, precision = 2^10, method = "kernel", ...)

Arguments

`posterior`	Vector representing a posterior distribution.
`x`	The value of which to get the approximate probability.
`precision`	Number of points of density data. See the `n` parameter in `density`.
`method`	Density estimation method. Can be `"kernel"` (default), `"logspline"` or `"KernSmooth"`.
`...`	Currently not used.

Examples

library(bayestestR)
posterior <- distribution_normal(n = 10)
density_at(posterior, 0)
density_at(posterior, c(0, 1))
