Density of a truncated Student's t distribution

Calculates the density of a truncated Student's t distribution.

Usage

dtt(x, mu = 0, sd = 1, df = 3, range = c(0, Inf), log = FALSE)

Arguments

x

A numeric vector at which to evaluate the density.

mu

A numeric scalar representing the mean of the underlying t distribution. Defaults to 0.

sd

A numeric scalar representing the standard deviation of the underlying t distribution. Defaults to 1.

df

A numeric scalar representing the degrees of freedom of the underlying t distribution. Defaults to 3.

range

A numeric vector of length 2 specifying the lower and upper truncation bounds. Defaults to c(0, Inf), indicating truncation from below at 0.

log

Logical; if TRUE, the natural logarithm of the density is returned. Defaults to FALSE.

Value

A numeric vector of the same length as x, containing the (log) density values of the truncated t distribution.
