titanic: Titanic Data

Description

Data describes the survival status of individual passengers on the British luxury passenger liner Titanic that sank when it struck an iceberg on April 1912, on its maiden voyage to New York City from Southampton, England (Weisberg, 2003). Information were obtained from Encyclopedia Titanica. The variables on the dataset called titanic3 were made available by Harrell Jr (2001) and contains pclass, sex, embarked and survival status for each person on the board of the Titanic. pclass refers to passenger class (1st, 2nd, 3rd), and is a proxy for socio-economic class. embarked indicates the place where the passenger embarked on the ship. The variables pclass and embarked were recoded in the present version of the dataset. These data were used to compute prevalence ratios and corresponding confidence intervals.
