ExoticStatistics | R Documentation |
This decorator adds methods for more complex statistical methods including p-norms, survival and hazard functions and anti-derivatives. If possible analytical expressions are exploited, otherwise numerical ones are used with a message.
Decorator objects add functionality to the given Distribution object by copying methods in the decorator environment to the chosen Distribution environment.
All methods implemented in decorators try to exploit analytical results where possible, otherwise numerical results are used with a message.

cdfAntiDeriv()
The cdf anti-derivative is defined by
acdf(a, b) = \int_a^b F_X(x) dx
where X is the distribution, F_X is the cdf of the distribution X and
a, b are the lower
and upper
limits of integration.
ExoticStatistics$cdfAntiDeriv(lower = NULL, upper = NULL)
lower
(numeric(1)
Lower bounds of integral.
upper
(numeric(1)
Upper bounds of integral.
survivalAntiDeriv()
The survival anti-derivative is defined by
as(a, b) = \int_a^b S_X(x) dx
where X is the distribution, S_X is the survival function of the distribution
X and a, b are the lower
and upper
limits of integration.
ExoticStatistics$survivalAntiDeriv(lower = NULL, upper = NULL)
lower
(numeric(1)
Lower bounds of integral.
upper
(numeric(1)
Upper bounds of integral.
survival()
The survival function is defined by
S_X(x) = P(X ≥ x) = 1 - F_X(x) = \int_x^∞ f_X(x) dx
where X is the distribution, S_X is the survival function, F_X is the cdf and f_X is the pdf.
ExoticStatistics$survival(..., log = FALSE, simplify = TRUE, data = NULL)
...
(numeric())
Points to evaluate the function at Arguments do not need
to be named. The length of each argument corresponds to the number of points to evaluate,
the number of arguments corresponds to the number of variables in the distribution.
See examples.
log
(logical(1))
If TRUE
returns the logarithm of the probabilities. Default is FALSE
.
simplify
logical(1)
If TRUE
(default) simplifies the return if possible to a numeric
, otherwise returns a
data.table::data.table.
data
array
Alternative method to specify points to evaluate. If univariate then rows correspond with number
of points to evaluate and columns correspond with number of variables to evaluate. In the special
case of VectorDistributions of multivariate distributions, then the third dimension corresponds
to the distribution in the vector to evaluate.
hazard()
The hazard function is defined by
h_X(x) = f_X/S_X
where X is the distribution, S_X is the survival function and f_X is the pdf.
ExoticStatistics$hazard(..., log = FALSE, simplify = TRUE, data = NULL)
...

to be named. The length of each argument corresponds to the number of points to evaluate,
the number of arguments corresponds to the number of variables in the distribution.

cumHazard()
The cumulative hazard function is defined analytically by
