Transient vasoconstriction in skin of fingers
=============================================
Data: vaso.dat
Keywords: Logistic regression.
Description: A study was made into the effect of volume and rate of
air inspired by human subjects on the occurrence of transient
vasoconstriction in the skin of the fingers. A total of 39 observations were
obtained on these variables from 3 subjects in a laboratory. The data are
assumed to be independent (including those on the same subject).
Number of observations: 39 
Variable   Description  
volume     Volume of air inspired by subject.  
rate       Rate of air inspired by subject.  
survive    Binary variable: occurrence of transient vasoconstriction 
           in the skin of the fingers=1, no-occurence=0
