%description
A Davidian curve defines a seminonparametric density, whose shape and
flexibility can be tuned by easy to estimate parameters. Since a special
case of a Davidian curve is the standard normal density, Davidian curves
can be used for relaxing normality assumption in statistical applications
(Zhang & Davidian, 2001) <doi:10.1111/j.0006-341X.2001.00795.x>. This
package provides the density function, the gradient of the loglikelihood
and a random generator for Davidian curves.
