evap: Data on soil evaporation.

Description

Data from 46 consecutive days on weather variables used to estimate amount of evaporation from the soil.

Usage

data(evap)

source

Freund, R.J. (1979) Multicollinearity etc., Some "New" Examples. Proceedings of the Statistical Computing Section, *4*, 111-112.

Details

The idea of the data is to predict the amount of evaporation given the other variables. Note that the "average" values are scaled differently from the others, this is more an area under the curve measure representing the total/average value. This dataset was entered by hand from a low quality copy of the paper. If you find any typos, please e-mail them to the package maintainer.
