lqd2dens: Function for converting log quantile densities to densities

Description

Function for converting log quantile densities to densities

Usage

lqd2dens(
  lqd,
  lqdSup = seq(0, 1, length.out = length(lqd)),
  dSup,
  useSplines = TRUE
)

Value

dens density values on dSup

Arguments

lqd

log quantile density on lqdSup

lqdSup

support forlqd domain - must begin at 0 and end at 1

dSup

support for Density domain - max and min values mark the boundary of the support.

useSplines

fit spline to the lqd when doing the numerical integration (default: TRUE)

Examples

x <- seq(0,2,length.out =512)
y.lqd <- rep(log(2), times = 512)
y <- lqd2dens(dSup=x, lqd = y.lqd) # should equate # 1/2
