The hermite_estimator_univar, x must be updated with observations prior to the use of the method.
# S3 method for hermite_estimator_univar
density(x, x_lower = NA, x_upper = NA, ...)
A hdensity_univar object whose underlying structure is a list containing the following components.
x: The points at which the density is calculated. density_vals: The density values at the points x. num_obs: The number of observations used to form the Hermite density estimates. N: The number of terms N in the Hermite series estimator.
A hermite_estimator_univar object.
A numeric value. This value determines the lower limit of x values at which to evaluate the density.
A numeric value. This value determines the upper limit of x values at which to evaluate the density.
Additional arguments for the dens function.
