prodscore: Soil productivity

In alr4: Data to Accompany Applied Linear Regression 4th Edition

Description

Soil productivity scores for farms in townships in four counties in the Minneapolis St. Paul metropolitan area, 1981-82. The goal is to see if the productivity score is a good predictor of the assessed value of the farmland. If so, then productivity score could be used to set assesed value for farms enrolled in the “green acres” program that requires that urban farmland be taxed at its agricultural value only without regard to development potential.

County

Name of the county

Value
