A call to csem() results in an object with at least
two class attributes. The first class attribute is always cSEMResults no matter
the type of data or model provided.
The second is one of cSEMResults_default, cSEMResults_multi, or
cSEMResults_2ndorder and depends on the estimated model and/or the type of
data provided to the .model and .data arguments of csem().
The third class attribute cSEMResults_resampled is only added if resampling
was conducted.
Depending on the type of data and/or model provided three different output types exists.
This will be the structure for the vast majority of applications.
If the data is a single matrix or data.frame with no id-column,
the result is a list with elements:
$EstimatesA list containing a list of estimated quantities.
$InformationA list containing a list of additional information.
The resulting object has classes cSEMResults and cSEMResults_default.
If the data provided is a single matrix or data.frame containing
an id-column to split the data by G group levels
or if a list of G datasets is provided, the resulting object is a list of G
lists, where G is equal to the number of groups or the number of datasets
in the list of datasets provided. Each of the G list elements is itself
a cSEMResults_default object. Hence its structure is identical to
the structure described in _default.
The resulting object has classes cSEMResults and cSEMResults_multi.
A special output is generated if the model to estimate contains hierarchical constructs
and the "2stage" or "mixed" approach is used to estimate the model. In this case
the resulting object is a list containing two elements First_stage and
Second_stage.
Each list element is itself a cSEMResults_default object. Hence its structure is identical to
the structure described in _default.
If .resample_method = "bootstrap" or .resample_method = "jackknife", resamples
are attached to each object. For objects of class cSEMResults_default the resamples are
attached to .object$Estimates$Estimates_resample. For objects of class
cSEMResults_multi the same is done by group. For objects of class
cSEMResults_2ndorder the resamples are attached to the
.object$Second_stage$Information$Resamples. All objects containing
these elements gain the cSEMResults_resampled class.
