Data on fresh milk expenditure.

Description

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

Usage

data(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.

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.
