Noncentral F Distribution Class
Mathematical and statistical functions for the Noncentral F distribution, which is commonly used in ANOVA testing and is the ratio of scaled Chi-Squared distributions.
The Noncentral F distribution parameterised with two degrees of freedom parameters, μ, ν, and location, λ, # nolint is defined by the pdf,
f(x) = ∑_{r=0}^{∞} ((exp(-λ/2)(λ/2)^r)/(B(ν/2, μ/2+r)r!))(μ/ν)^{μ/2+r}(ν/(ν+xμ))^{(μ+ν)/2+r}x^{μ/2-1+r}
for μ, ν > 0, λ ≥ 0.
Returns an R6 object inheriting from class SDistribution.
The distribution is supported on the Positive Reals.
FNC(df1 = 1, df2 = 1, location = 0)

nameFull name of distribution.
short_nameShort name of distribution for printing.
descriptionBrief description of the distribution.
packagesPackages required to be installed in order to construct the distribution.
new()
Creates a new instance of this R6 class.
FDistributionNoncentral$new( df1 = NULL, df2 = NULL, location = NULL, decorators = NULL )
df1(numeric(1))
First degree of freedom of the distribution defined on the positive Reals.
df2(numeric(1))
Second degree of freedom of the distribution defined on the positive Reals.
location(numeric(1))
Location parameter, defined on the Reals.
decorators(character())
Decorators to add to the distribution during construction.
mean()
The arithmetic mean of a (discrete) probability distribution X is the expectation
E_X(X) = ∑ p_X(x)*x
with an integration analogue for continuous distributions.
FDistributionNoncentral$mean(...)
...Unused.
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.
FDistributionNoncentral$variance(...)
...Unused.
setParameterValue()
Sets the value(s) of the given parameter(s).
FDistributionNoncentral$setParameterValue( ..., lst = NULL, error = "warn", resolveConflicts = FALSE )
...ANY
Named arguments of parameters to set values for. See examples.
lst(list(1))
Alternative argument for passing parameters. List names should be parameter names and list values
are the new values to set.
error(character(1))
If "warn" then returns a warning on error, otherwise breaks if "stop".
resolveConflicts(logical(1))
If FALSE (default) throws error if conflicting parameterisations are provided, otherwise
automatically resolves them by removing all conflicting parameters.
clone()
The objects of this class are cloneable with this method.
FDistributionNoncentral$clone(deep = FALSE)
deepWhether to make a deep clone.
