Objects from the Class
Objects can be created by calls of the form Td(df)
.
This object is a $t$ distribution.Slots
img
- Object of class
"Reals"
: The domain of this distribution has got dimension 1
and the name "Real Space". param
- Object of class
"TParameter"
: the parameter of this distribution (df),
declared at its instantiation r
- Object of class
"function"
: generates random numbers (calls function rt
) d
- Object of class
"function"
: density function (calls function dt
) p
- Object of class
"function"
: cumulative function (calls function pt
) q
- Object of class
"function"
: inverse of the cumulative function (calls function qt
) .withArith
- logical: used internally to issue warnings as to
interpretation of arithmetics
.withSim
- logical: used internally to issue warnings as to
accuracy
.logExact
- logical: used internally to flag the case where
there are explicit formulae for the log version of density, cdf, and
quantile function
.lowerExact
- logical: used internally to flag the case where
there are explicit formulae for the lower tail version of cdf and quantile
function
Symmetry
- object of class
"DistributionSymmetry"
;
used internally to avoid unnecessary calculations.

.Methods
- initialize
signature(.Object = "Td")
: initialize method - df
signature(object = "Td")
: returns the slot df of the parameter of the distribution - df<-
signature(object = "Td")
: modifies the slot df of the parameter of the distribution - ncp
signature(object = "Td")
: returns the slot ncp of the parameter of the distribution - ncp<-
signature(object = "Td")
: modifies the slot ncp of the parameter of the distribution
Ad hoc methods
For R Version <2.3.0< code=""> ad hoc methods are provided for slots q
, r
if ncp!=0
;
for R Version >=2.3.0
the methods from package stats are used.2.3.0<>
