Phenobarb

This dataset contains longitudinal data on Phenobarbital concentration levels in newborn infants.

datasets

Provides methods for detecting influential subjects in
longitudinal data, particularly when observations are collected at
irregular time points. The package identifies subjects whose response
trajectories deviate substantially from population-level patterns,
helping to diagnose anomalies and undue influence on model estimates.

Phenobarb function

A data frame with 744 observations on the following 7 variables:<dl>
 <dt>Subject</dt>
<dd>An ordered factor identifying the infant.</dd> <dt>Wt</dt>
<dd>A numeric vector giving the birth weight of the infant (kg).</dd> <dt>Apgar</dt>
