Method new()

Creates a new instance of this R6 class.

Usage

LogisticKernel$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

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

Arguments

x

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

upper

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

---

Method cdfSquared2Norm()

The squared 2-norm of the cdf 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

LogisticKernel$cdfSquared2Norm(x = 0, upper = 0)

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

LogisticKernel$variance(...)

Arguments

...

Unused.

---

Method clone()

The objects of this class are cloneable with this method.

Usage

LogisticKernel$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
