Hello!
Please, anybody help me.
Can I calculate area of density was created by:
D <- density(x)
In other words I want to know area under curve 'plot(D)'
That should be 1.
and It's good to calculate area before and after 0 separately.
That's harder, but a good approximation should be sum(x < 0)/length(x)
and sum(x > 0)/length(x).
