Description Objects from the Class Slots Methods Author(s) Examples
Objects of class /distri/ indicate the main
characteristics of the distribution with the help of a
/proba/
object, but also the number of elementary number of
simulations, and the numerical values to attribute to the necessary
parameters.
Objects can be created by calls of the form new("distri",...)
where ... will be replaced by its slots when default values are not
convenient.
probab
:Object of class "probab"
to define
the family and the fixed parameters.
nbdraw
:Object of class "numeric(1)"
to define
the number of simulations when it is not given by the number of rows
of the slot parand
and these are constant over all the simulations.
parand
:Object of class "matrix"
and
numeric
giving the necessary additional parameters for the
simulation. Each row of the matrix correspond to a simulation. This
matrix structure was implemented to allow different value between
simulations. For the moment, the matrix has got only two columns for
the central value and the variation coefficient. This gives a unified
parameterization of all distributions and encompass the degenerate
cases for extreme values of the variation coefficient. No need to
give this matrix some dimnames.
see print8distri
for the details.
