Normalize distribution

Normalizes the distribution so that the total mass equals 1.

normalize(d, qp)

Arguments

d

A vector with length(qp) elements representing the unscaled density at each quadrature point.

qp

Vector of equally spaced quadrature points.

Value

A vector of length(d) elements with the prior density estimate at each quadature point.

Note

: Internal function

Examples

dscore:::normalize(c(5, 10, 5), qp = c(0, 1, 2))
#> [1] 0.25 0.50 0.25

sum(dscore:::normalize(rnorm(5), qp = 1:5))
#> [1] 1
