mlbw: Matched Low Birth Weight data

In dardisco/LogisticDx: Diagnostic Tests for Logistic Regression Models

Description

Matched Low Birth Weight data

Format

A data.frame with 112 observations (rows) and 9 variables (columns).

Details

This data was collected as part of a larger study at Bayside Medical Center, Springfield, Massachusetts. It contains information on 56 cases (of low birth weight deliveries) and an equal number of age-matched controls.

The observed variable values were modified to protect patient confidentiality.

A one-to-one matched set was created from the low birth weight data. For each woman who gave birth to a low birth weight baby, a mother of the same age was randomly selected who did not give birth to a low birth weight baby. For three mothers aged < 17, it was not possible to identify a match.
