R/SDistribution_FDistributionNoncentral.R
FDistributionNoncentral.RdMathematical and statistical functions for the Noncentral F distribution, which is commonly used in ANOVA testing and is the ratio of scaled Chi-Squared distributions.
Returns an R6 object inheriting from class SDistribution.
The Noncentral F distribution parameterised with two degrees of freedom parameters, \(\mu, \nu\), and location, \(\lambda\), # nolint is defined by the pdf, $$f(x) = \sum_{r=0}^{\infty} ((exp(-\lambda/2)(\lambda/2)^r)/(B(\nu/2, \mu/2+r)r!))(\mu/\nu)^{\mu/2+r}(\nu/(\nu+x\mu))^{(\mu+\nu)/2+r}x^{\mu/2-1+r}$$ for \(\mu, \nu > 0, \lambda \ge 0\).
The distribution is supported on the Positive Reals.

)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 $$E_X(X) = \sum p_X(x)*x$$ with an integration analogue for continuous distributions.
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.
