Description

Wooldridge Source: G.E. Battese, R.M. Harter, and W.A. Fuller (1988), “An Error-Components Model for Prediction of County Crop Areas Using Survey and Satellite Data,” Journal of the American Statistical Association 83, 28-36. This small data set is reported in the article. Data loads lazily.

Usage

Format

A data.frame with 37 observations on 5 variables:

• county: county number

• cornhec: corn per hectare

• soyhec: soybeans per hectare

• cornpix: corn pixels per hectare

• soypix: soy pixels per hectare

Notes

You could use these data to illustrate simple regression when the population intercept should be zero: no corn pixels should predict no corn planted. The same can be done with the soybean measures in the data set.
