I want to check whether (x,y) follows a bivariate normal
distribution or
not, using density plot or scatter plot. Is it possible to plot a
bivariate
density in R. I cant find any.
wireframe and package functions for mv-normal distribution?
require(MASS)
?kde2d
OR
??kde which on my machine pulls up quite a 2 alternatives in my
collection of installed packages: ade4::s.kde2d, KernSmooth::bkde2D,
and maybe ks::kde.
