Cosine Kernel
Mathematical and statistical functions for the Cosine kernel defined by the pdf,
f(x) = (π/4)cos(xπ/2)
over the support x ε (-1,1).
distr6::Distribution -> distr6::Kernel -> Cosine
nameFull name of distribution.
short_nameShort name of distribution for printing.
descriptionBrief description of the distribution.
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.
Cosine$pdfSquared2Norm(x = 0, upper = Inf)
x(numeric(1))
Amount to shift the result.
upper(numeric(1))
Upper limit of the integral.
cdfSquared2Norm()
The squared 2-norm of the cdf is defined by
\int_a^b (F_X(u))^2 du
where X is the Distribution, F_X is its pdf and a, b are the distribution support limits.
Cosine$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.
Cosine$variance(...)
...Unused.
clone()
The objects of this class are cloneable with this method.
Cosine$clone(deep = FALSE)
deepWhether to make a deep clone.
