    %% Create a GroupedData Object from Dataset  
% This example uses data collected on 59 preterm infants given
% phenobarbital during the first 16 days after birth. Each infant received
% an initial dose followed by one or more sustaining doses by intravenous
% bolus administration. A total of between 1 and 6 concentration
% measurements were obtained from each infant at times other than dose
% times, for a total of 155 measurements. Infant weights and APGAR scores
% (a measure of newborn health) were also recorded. Data is described in
% <docid:simbio_ref.bua3l3_-2>, a study funded by the NIH/NIBIB grant
% P41-EB01975.

% |GroupVariableName| and |IndpendentVariableName| have been automatically
