data_dropout: Dropout Dataset

In TimeDepFrail: Time Dependent Shared Frailty Cox Model

Dropout Dataset

Description

This dataset is extracted from an administrative database provided by a non-specified university and tracks students enrolled in 2012 over three academic years (or 6 semesters). We are interested in understanding what factors lead to students dropping out. Dropout students with a time-instant in the first semester have been removed, for internal reasons (the university cannot take preventive action to reduce or avoid their withdrawal). The students are followed for at most 3 academic years or, equivalently, 6 semesters (follow-up periods), from the first day of lecture up to the time-instant of withdrawal (i.e. survival event) or the end of the academic year.

Usage

data_dropout

Format

A data frame with 4448 rows and 4 columns:

Gender

Categorical covariate (Male or Female).

CFUP

Standardized numerical covariate indicating the number of credits \ passed by the students by the end of the first semester.

time_to_event

Time (in semesters) at which a student decides to leave the university. \ A value greater than 6.0 indicates the student did not drop out during the follow-up (e.g. 6.1 semesters)

group

Categorical variable indicating the student's course of study, with 16 different levels from CosA, CosB, ... , CosP.
