make.calfun {survey}

Calibration metrics

Description

Create calibration metric for use in calibrate. The function F is the link function described in section 2 of Deville et al. To create a new calibration metric, specify F-1 and its derivative. The package provides cal.linear, cal.raking, cal.logit, which are standard, and cal.sinh from the CALMAR2 macro, for which F is the derivative of the inverse hyperbolic sine.

Usage

make.calfun(Fm1, dF, name)

Arguments

Fm1

Function F-1 taking a vector u and a vector of length 2, bounds.

dF

Derivative of Fm1 wrt u: arguments u and bounds

name

Character string to use as name

Value

An object of class "calfun"
