validate_Density: Validator for the S3 class 'Density'
In hericks/KDE: Kernel Density Estimation

Description Usage Arguments Details Special Attention See Also

This function serves as a validator for the S3 class Density. See 'Details' for further information and potential flaws.

1	validate_Density(x)

`x`	an `R` object to validate as object of S3 class `Density`.

The validator validate_Density can be used to verify objects as formally correct S3 objects of class Density. In particular the formal structure is ensured and validate_IntegrableFunction is called internally. Additionally this function tries to (see 'Special Attention') validate the additional conditions of valid density functions (as specified in the first 'Details'-paragraph of Density).

Like all numerical routines, validate_Density can evaluate the represented function on a finite set of points only. If the represented function returns valid results over nearly all its range, it is possible that this function misses unexpected/wrong return values. Thus, using Density or validate_Density to construct and validate objects representing integrable functions is not sufficient to ensure the properties [1-5] listed in the first 'Details'-paragraph of Density, but serves more as a sanity-check.
