dtrunc: Probability density function of truncated random variables
Description
This function computes values for the probability density function
of a truncated random variable.
Usage
dtrunc(x, spec, a = -Inf, b = Inf, ...)
Arguments
x
A numeric vector of quantile values
spec
a character value that specifies the underlying probability distribution
a
a numeric value for the lower bound of the random variable
b
a numeric value for the upper bound of the random variable
...
other arguments are are passed to the corresponding quantile function
Value
A vector of density function values.
Details
The R function is used to access the required probability density and cumulative
distribution functions of the underlying unrestricted random variable.
