Computes the mode of the generalized hyperbolic function.
ghMode(alpha = 1, beta = 0, delta = 1, mu = 0, lambda = -1/2)a numeric value, the mode of the generalized hyperbolic distribution
first shape parameter.
second shape parameter, should in the range (0, alpha).
scale parameter, must be zero or positive.
location parameter, by default 0.
defines the sublclass, by default \(-1/2\).
The meanings of the parameters correspond to the first
parameterization, see gh for further details.
