This package contains 31 data sets provided by Singer and Willet (2003) with their book, Applied longitudinal data analysis: Modeling change and event occurrence, that are suitable for longitudinal mixed effects modelling, longitudinal structural equation modelling, and survival analysis. All the data sets in this package are real data from real studies; however, most were modified by Singer and Willet (2003) for the illustration of statistical methods, so they may not match the results of the original studies.
There are eleven data sets for longitudinal mixed effects modelling:
-
?deviant_tolerance: Adolescent tolerance of deviant behaviour (Chapter 2) -
?early_intervention: Early educational interventions and cognitive performance (Chapter 3) -
?alcohol_use_1: Adolescent and peer alcohol use (Chapters 4 and 6) -
?reading_scores: Peabody Individual Achievement Test reading scores (Chapter 5) -
?dropout_wages: High school dropout labour market experiences (Chapters 5 and 6) -
?depression_unemployment: Unemployment and depression (Chapter 5) -
?antidepressants: Antidepressant medication and positive mood (Chapter 5) -
?berkeley: Berkeley Growth Study (Chapter 6) -
?externalizing_behaviour: Externalizing behaviour in children (Chapter 6) -
?cognitive_growth: Cognitive growth in children (Chapter 6) -
?opposites_naming: Opposites naming task (Chapter 7)
There is one data set for longitudinal structural equation modelling:
-
?alcohol_use_2: Adolescent alcohol consumption and peer pressure (Chapter 8)
There are twenty data sets for survival analysis:
-
?teachers: Years to special education teacher turnover (Chapters 9 and 10) -
?cocaine_relapse_1: Weeks to cocaine relapse after treatment (Chapter 10) -

?cocaine_relapse_2: Days to cocaine relapse after abstinence (Chapter 15) -
?psychiatric_discharge: Days to psychiatric hospital discharge (Chapter 15) -
?physicians: Physician career history (Chapter 15) -
?monkeys: Piagetian monkeys (Chapter 15)
