\title{Generalized Hyperbolic Student-t Mode}


\description{
    
    Computes the mode of the generalized hyperbolic 
    Student-t distribution.
    
}


\usage{
ghtMode(beta = 0.1, delta = 1, mu = 0, nu = 10)
}


\arguments{

    \item{beta, delta, mu}{
        numeric values.
        \code{beta} is the skewness parameter in the range \code{(0, alpha)};
        \code{delta} is the scale parameter, must be zero or positive; 
        \code{mu} is the location parameter, by default 0.
        These are the parameters in the first parameterization.
        }
    \item{nu}{
        a numeric value, the number of degrees of freedom.
        Note, \code{alpha} takes the limit of \code{abs(beta)}, 
        and \code{lambda=-nu/2}.
        }
    
}


\value{
    
    returns the mode for the generalized hyperbolic Student-t
    distribution. A numeric value.
    
}
