help with bivariate density plot question
...ry(Genkern) to
get a estimated bivariate density and corresponding plots as follows:
new.data.normal<-data.normal[!is.na(data.normal[,2]),]
x<-new.data.normal[,2]
y<-new.data.normal[,3]
op <- KernSur(x,y, xgridsize=50, ygridsize=50, correlation=0.4968023,
xbandwidth=1, ybandwidth=1)
#3D density plot
