In earth: Multivariate Adaptive Regression Splines

Titanic data with incomplete cases removed

Description

Titanic data with incomplete cases, passenger names, and other details removed.

Format

A data frame with 1046 observations on 6 variables.

pclass	passenger class, unordered factor: 1st 2nd 3rd
survived	integer: 0 or 1
sex	unordered factor: male female
age	age in years, min 0.167 max 80.0
sibsp	number of siblings or spouses aboard, integer: 0...8
parch	number of parents or children aboard, integer: 0...6

Source

This dataset is included in the earth package because it is a convenient vehicle for illustrating earth's GLM and factor handling.

The dataset was compiled by Frank Harrell and Robert Dawson: https://hbiostat.org/data/repo/titanic.html

For this version of the Titanic data, passenger details and incomplete cases were deleted and the name changed to etitanic to minimize confusion with other versions ("e" because it is part of the earth package).

Note that survived is an integer (it should arguably be a logical).

In this data the crew are conspicuous by their absence.

How etitanic was built:

    load("titanic3") # from Harrell's web site
    # discard name, ticket, fare, cabin, embarked, body, home.dest
    etitanic <- titanic3[,c(1,2,4,5,6,7)]
    etitanic <- etitanic[!is.na(etitanic$age),]
    save(etitanic, file="etitanic.rda")
