wagnerGrowth: Wagner's Hannover Employment Growth Data

Description

Wagner (1994) investigates the rate of employment growth (y) as function of percentage of people engaged in producation activities (PA) and higher services (HS) and of the growth of these percentages (GPA, GHS) during three time periods in 21 geographical regions of the greater Hannover area.

Usage

data(wagnerGrowth, package="robustbase")

Arguments

Format

A data frame with \(21 \times 3 = 63\) observations (one per Region x Period) on the following 7 variables.

Region

a factor with 21 levels, denoting the corresponding region in Hannover (conceptually a “block factor”).

PA

numeric: percent of people involved in production activities.

GPA

growth of PA.

HS

a numeric vector

GHS

a numeric vector

y

a numeric vector

Period

a factor with levels 1:3, denoting the time period, 1 = 1979-1982, 2 = 1983-1988, 3 = 1989-1992.
