Wagner's Hannover Employment Growth Data
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.
data(wagnerGrowth, package="robustbase")
A data frame with 21 * 3 = 63 observations
(one per Region x Period) on the following 7 variables.
Regiona factor with 21 levels, denoting
the corresponding region in Hannover (conceptually a “block
factor”).
PAnumeric: percent of people involved in production activities.
GPAgrowth of PA.
HSa numeric vector
GHSa numeric vector
ya numeric vector
Perioda factor with levels 1:3,
denoting the time period, 1 = 1979-1982, 2 = 1983-1988, 3 = 1989-1992.
