Estimator: Function to compute estimates

Description

The function Estimator provides a general way to compute estimates.

Usage

Estimator(x, estimator, name, Infos, asvar = NULL, nuis.idx,
          trafo = NULL, fixed = NULL, asvar.fct, ...)

Arguments

x

(empirical) data

estimator

function: estimator to be evaluated on x.

name

optional name for estimator.

Infos

character: optional informations about estimator

asvar

optionally the asymptotic (co)variance of the estimator

nuis.idx

optionally the indices of the estimate belonging to nuisance parameter

fixed

optionally (numeric) the fixed part of the parameter

trafo

an object of class MatrixorFunction -- a transformation for the main parameter

asvar.fct

optionally: a function to determine the corresponding asymptotic variance; if given, asvar.fct takes arguments L2Fam((the parametric model as object of class L2ParamFamily)) and param (the p

...

further arguments to estimator.

Value

• An object of S4-class "Estimate".

Details

The argument criterion has to be a function with arguments the empirical data as well as an object of class "Distribution" and possibly ....
