Description

The E4.4 data frame has 40 rows and 3 columns.

Usage

data(E4.4)

Format

This data frame contains the following columns:

QUAL

a numeric vector, a quality measure made using psychometric methods from results of questionares.

X.1

a numeric vector, an indicator variable for private ownership.

X.2

a numeric vector, an indicator variable for private for profit ownership.

Details

The quality data, QUAL, is constructed from questionares given to users of such services in the state of Illinois. Multiple services in the state of Illinois was scored using this method. The indicator variables was constructed to give first (X.1) a comparison between private and public services, then (X.2) a comparison between private not-for-profit and private for profit services.

Trucks can be weighted by two methods. In one, a truck needs to go into a weighting station and each axle is weighted by conventional means. The other is newer and a somewhat experimental method where a thin pad is placed on the highway and axles are weighted as trucks pass over it. Former weight are called static weights (sw) while later are called weights in motion (wim).
