Variance function estimation for models proposed by W. Sadler in his variance function program
('VFP', <http://www.aacb.asn.au/resources/useful-tools/variance-function-program-v14>). 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.

Vegetated Filter Strip and Erosion Model

Empirical models for runoff, erosion, and phosphorus loss
across a vegetated filter strip, given slope, soils, climate, and
vegetation (Gall et al., 2018) <doi:10.1007/s00477-017-1505-x>.
It also includes functions for deriving climate parameters from
measured daily weather data, and for simulating rainfall. Models
implemented include MUSLE (Williams, 1975) and APLE (Vadas et al.,
2009 <doi:10.2134/jeq2008.0337>).

Vector Generalized Linear and Additive Models
R (>= 2.4.0), splines, methods, stats, stats4
Vector generalized linear and additive models, and
associated models (Reduced-Rank VGLMs, Quadratic RR-VGLMs,
Reduced-Rank VGAMs). This package fits many models and
distribution by maximum likelihood estimation (MLE) or
penalized MLE. Also fits constrained ordination models in
ecology.
