Trait Kernel

pub trait Kernel<F: KDEFloat> {
    // Required method
    fn pdf(&self, x: F) -> F;
}

Shared behavior for kernel functions.

Well-behaved kernel functions exhibit three properties:

1. The function is non-negative and real-valued.
2. The function should integrate to 1.
3. The function should be symmetrical.

Required Methods

fn pdf(&self, x: F) -> F

Returns the probability density function for a value x.
