Glucose

<p>Intra-day precision of arterial glucose measurement on the Precision PCx instrument 
  (Abbott Laboratories, Abbott Park, Illinois, USA).  
  The data were kindly provided by Peter Watkinson, The John Radcliffe Hospital, Oxford, UK.  
  They provide an excellent example of a situation where a simple variance function 
  should be imposed in preference to accepting the fit of one of the flexible functions.</p>

datasets

Variance function estimation for models proposed by W. Sadler in his variance function program
('VFP', www.aacb.asn.au/AACB/Resources/Variance-Function-Program). Here, the idea is
to fit multiple variance functions to a data set and consequently assess which function reflects
the relationship 'Var ~ Mean' best. For 'in-vitro diagnostic' ('IVD') assays modeling this relationship
is of great importance when individual test-results are used for defining follow-up treatment of patients.
