NormalKernel: Normal Kernel

In distr6: The Complete R6 Probability Distributions Interface

Normal Kernel

Description

Mathematical and statistical functions for the NormalKernel kernel defined by the pdf,

f(x) = exp(-x^2/2)/√{2π}

over the support x ε R.

Details

We use the erf and erfinv error and inverse error functions from pracma.

Method new()

Creates a new instance of this R6 class.

Usage

NormalKernel$new(decorators = NULL)

Arguments

decorators

(character())
Decorators to add to the distribution during construction.

---

Method pdfSquared2Norm()

The squared 2-norm of the pdf is defined by

\int_a^b (f_X(u))^2 du

where X is the Distribution, f_X is its pdf and a, b are the distribution support limits.

Usage

NormalKernel$pdfSquared2Norm(x = 0, upper = Inf)

Arguments

x

(numeric(1))
Amount to shift the result.

upper

(numeric(1))
Upper limit of the integral.

---

Method variance()

The variance of a distribution is defined by the formula

var_X = E[X^2] - E[X]^2

where E_X is the expectation of distribution X. If the distribution is multivariate the covariance matrix is returned.

Usage

NormalKernel$variance(...)

Arguments

...

Unused.

---

Method clone()

The objects of this class are cloneable with this method.

Usage

NormalKernel$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
