pondfrog1: Fake Data: Number of Frogs in Ponds

In blmeco: Data Files and Functions Accompanying the Book "Bayesian Data Analysis in Ecology using R, BUGS and Stan"

Description

Simulated data of which the true model is known. Can be used to play with model selection. This is a simplified version of the pondfrog -example (see pondfrog)

Usage

data(pondfrog1)

Format

A data frame with 130 observations on the following 4 variables.

frog

a numeric vector

ph

a numeric vector

waterdepth

a numeric vector

temp

a numeric vector

Details

The code used to simulate the data was: set.seed(333) frog.mu <- exp(3.5 + 0.2*(temp-mean(temp))+0.1*(ph-mean(ph)) - 0.3*(waterdepth-mean(waterdepth)) ) frog <- rpois(n, lambda=frog.mu)

For the simulation of the explanatory variables, see help file for the pondfrog data

Examples

data(pondfrog1)
pairs(pondfrog1)
