⚠️There's a newer version (1.4.4) of this package.Take me there.
VFP (version 1.4.1)
Variance Function Program
Description
Variance function estimation for models proposed by W. Sadler in his variance function program
('VFP', ). 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.
