milk {saens}

milk: Data on fresh milk expenditure.

Description

Data on fresh milk expenditure, used by Arora and Lahiri (1997) and by You and Chapman (2006).

Usage

milk

Format

A data frame with 43 observations on the following 6 variables.

SmallArea

areas of inferential interest.

ni

sample sizes of small areas.

yi

average expenditure on fresh milk for the year 1989 (direct estimates for the small areas).

SD

estimated standard deviations of yi.

var

variance sampling from the direct estimator (yi) for each area

CV

estimated coefficients of variation of yi.

MajorArea

major areas created by You and Chapman (2006). These areas have similar direct estimates and produce a large CV reduction when using a FH model.
