Description Value References See Also
An object of class emdi that represents point predictions of regional
disaggregated indicators. Optionally it also contains corresponding MSE
estimates. Depending on the estimation the object is also of class direct
or model. For each provided model-based approach an additional class is assigned:
the standard Fay-Herriot approach ("fh"), and the empirical best prediction
("ebp"). Objects of these classes have methods for the generic functions
estimators
, print
, plot
(only for
class model), and summary
.
The following components are always included in an emdi object:
|
a list containing an image of the function call that produced the object. |
|
a formula of fixed effects used in the nested error linear
regression (see also |
|
a list with following components: |
N_dom_smp | number of domains in the sample. | |
N_dom_unobs | number of out-of-sample domains. Not filled for class direct. | |
N_pop | total number of units in population. Not filled for class direct. | |
N_smp | total number of units in sample. | |
pop_domains_vec | an arranged vector of the domain indicator variable. Not filled for class direct. | |
smp_data | an arranged data set of sample data. Not filled for class direct. | |
smp_domains | a character naming the domain indicator variable. | |
smp_domains_vec | an arranged vector of the domain indicator variable. | |
|
data frame containing estimates for indicators per domain. |
|
character returning the method for the estimation of the optimal lambda (for class ebp), here "reml", or a list returning method for the estimation of the variance of the random effect and the applied MSE estimation (for class fh). Not filled for class direct. |
|
for class ebp, an object returned by the lme function of type "lme"
and representing a fitted linear mixed-effects model (for

data frame containing MSE estimates corresponding to the
point predictions in |
|
character returning the selected transformation
type (see also |
|
a list with two elements, |
|
a matrix with domains as rows and indicators as columns. The cells contain the number of successful bootstraps for each combination. Not filled for class model. |
