Description

Usage

Rhizoc

Details

This dataset appeared Zhang (2002) and was modeled using the Binomial Logit-normal spatial model. It consists of counts of the root disease Rhizoctonia root rot present in barey plants collected at 100 locations in the Cunningham farm in the north-west of the U.S. The sampling consisted on pulling from the ground 15 plants at each location. This dataset is a 100 by 4 matrix with rows (x_i , y_i , t_i), where x_i are the coordinates of the i^{th} sampling location, y_i is the total number of infected crown roots in the pulled plants at x_i, and t_i is the total number of crown roots in the pulled plants at x_i; see Zhang (2002) for further details.

Value

A data.frame with 100 observations and 5 variables.
