The function model
is used to describe sampling
models, specified by a symbolic description of the linear
predictor in formula
.

formula |
an object of class |
data |
an optional data frame, list or environment
containing variables used for a description of the model
in |
dist |
a sampling distribution of a response
variable; Defaults to |
ztrunc |
a logical value; Is the zero truncated?;
Defaults to |

a logical value; Be more verbose about the
process by displaying messages; Defaults to

The function model
is the first task on performing
an imprecise inferential framework. To tag this stage,
stage
has the character string model
that
is the name of environment called.
All details are identical to those of
formula
in glm
. In the
context of regression, y~0
represents a model that
does not involve any variables in data
. y~1
represents a model that involve an intercept term, but no
other variables in data
. y~.
represents a
model that involve all variables in data
.
An object of class imprecise
with the components:
xreg |
the logical value, Is the model described in
|
ztrunc |
the logical value supplied. |
formula |
the formula supplied. |
y |
the model reponse used in |
X |
the model matrix used in |
fit |
the object of classes |
stage |
the environment name called. |
init |
the list of estrimates for parameters in
|
The current version provides the only sampling model
poisson
. In the near future, binomial
and
normal
will be added.
