Survival of Premature Infants

Description

Survival of Premature Infants to be modeled using 5 potential explanatory variables.

Usage

  data("d.babysurvival")
  data("d.babysurvGr")

Format

d.babysurvival: A data frame with 246 observations on the following 6 variables.

Survival: binary, 1 means the infant survived
Weight: birth weight [g]
Age: pregnancy in weeks
Apgar1: A score indication the fitness of the infant at birth, scores 0 to 9
Apgar5: alternative score
pH: blood pH

n: Number of infants in the weight class
Survival.0, Survivl.1: Number of infants that died and survived, respectively
Weight: birth weight
