Mathematical and statistical functions for the LogisticKernel kernel defined by the pdf, $$f(x) = (exp(x) + 2 + exp(-x))^{-1}$$ over the support \(x \in R\).
distr6::Distribution -> distr6::Kernel -> LogisticKernel
nameFull name of distribution.
short_nameShort name of distribution for printing.
descriptionBrief description of the distribution.
new()Creates a new instance of this R6 class.
LogisticKernel$new(decorators = NULL)
decorators(character())
Decorators to add to the distribution during construction.
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.
LogisticKernel$pdfSquared2Norm(x = 0, upper = Inf)
x(numeric(1))
Amount to shift the result.
upper(numeric(1))
Upper limit of the integral.
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.
LogisticKernel$cdfSquared2Norm(x = 0, upper = 0)
x(numeric(1))
Amount to shift the result.
upper(numeric(1))
Upper limit of the integral.
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.
