## Usage

    data(swiss)

## Format

A data frame with 47 observations on 6 variables, each of which is in percent, i.e., in [0,100].

[,1] | Fertility | Ig, ``common standardized fertility measure''
[,2] | Agriculture | % involved in agriculture as occupation
[,3] | Examination | % ``draftees'' receiving highest mark
|  | on army examination
[,4] | Education | % education beyond primary school.
[,5] | Catholic | % catholic (as opposed to "protestant").
[,6] | Infant.Mortality | live births who live less than 1 year.

All variables but `Fertility' give proportions of the population.

## Description

(paraphrasing Mosteller and Tukey):

Switzerland, in 1888, was entering a period known as the ``demographic transition''; i.e., its fertility was beginning to fall from the high level typical of underdeveloped countries.

The data collected are for 47 seven French-speaking ``provinces'' at about 1888.

Here, all variables are scaled to [0,100], where in the original, all but `"Catholic"` were scaled to [0,1].
