Usage

data("FinnishElec")

Format

A data frame with 89 observations on the following 6 variables.

id

a character vector containing a unique identifier for each distribution firm

x

a numeric vector containing total expenditure (TOTEX*) (1000 Euros)

y1

a numeric vector containing weighted energy transmitted through the network (GWh of 0.4 kV equivalents)

y2

a numeric vector containing total length of the network (km)

y3

a numeric vector containing total number of customers connected to the network

z

a numeric vector containing the proportion of underground cables in the total network length.

Details

*TOTEX includes capital expenditure (CAPEX), controllable operational expenditure (OPEX), and estimated external cost of interruptions.
