dt.lap(x, df, ncp = 0, log = FALSE, normalize = c("central",
"integral", "none"), ...)
A numeric vector of quantiles
A numeric vector of degrees of freedom
A numeric vector of noncentrality parameters
logical; if TRUE
, log densities are returned
character. If central
, the normalization is such that the approxiamtion is exact when ncp=0
.
If integral
, numerical integration is performed such that the density integrate to 1 (not implemented yet).
If none
, no normalization is performed.
