salamander: Salamander mating dataset from McCullagh and Nelder (1989)

In mcll: Monte Carlo Local Likelihood Estimation

Description

The salamader dataset is from an experiment conducted at the University of Chicago in 1986 to study the extent to which mountain dusky salamanders from different populations would interbred. More detailed description of the data is given in McCullagh and Nelder (1989, Section 14.5).

The dataset contains 6 columns and 360 rows.

y

whether a mating was successful, Yes=1 and No=0.

female

identification number of the female salamander.

male

identification number of the male salamander.

group

group number; 1,2,3,4,5,6

experiment

experiment number; 1,2,3.

rbm

type of the male salamander; Rough Butt=1 and White Side=0

rbf

type of the female salamander; Rough Butt=1 and White Side=0

wsm

type of the male salamander; White Side=1 and Rough Butt=0

wsf

type of the female salamander; White Side=1 and Rough Butt=0

ww

interaction between female White Side and male White side; 1: a White Side female was crossed with a White Side male
