The functions dens, pp, qq and rl
create the diagnostic plots generated by plot.evd.
Similarly, bvdens, bvcpp and bvdp create
the diagnostic plots generated by plot.bvevd.
There are internal fitting, simulation, distribution and density
functions for each bivariate and multivariate parametric model,
which are called from functions such as rbvevd and
rmvevd. There also exists internal functions for the
calculation and plotting of dependence functions of
bivariate and trivariate models, which are called from
abvdep and atvdep.
The dependence functions are ultimately plotted by the low-level
functions bvdepfn and tvdepfn.
The function pcint calculates profile confidence intervals,
and is called from the function plot.profile.evd. The fitting
function fgev calls the internal functions fgev.quantile
and fgev.norm for fits under different parameterizations.
Marginal transformations are executed using mtransform.
The function ccop calculates condition copulas (i.e.
conditional distributions under uniform margins) for each
bivariate parametric model. This is needed to create the
conditional P-P plots generated by bvcpp.
The functions nsloc.transform, na.vals,
bvpost.optim, bvstart.vals and sep.bvdata
are used in the fitting of bivariate models. The function
mvalog.check checks and transforms the asy argument
for the multivariate asymmetric model.
