Rhizoc: Rhizoc Data

In geoCount: Analysis and Modeling for Geostatistical Count Data

Description

This data set contains the Rhizoc data set.

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.
