[R] integral in R






Hello All,

I have to create a variable that is a function of another one (already
created), its cumulative distribution function and the integral of this
cumulative distribution, with limits: 0 and the value of the variable.

To be clear, I have the variable called “cip”. And its cdf called “cdfcip”

I need to create the variable:

bip = cip + ((1 – cdfcip)^4)*integral((1-cdf(u))^4*du, 0, value of the
variable cip)

The problem: I don’t know how to do this integral. It is like a integral 
of
((1 – F(u))^4*du with limits 0 and a value c of individual i in case p of
the variable cip.

Does anybody knows how to do it? Am I clear with the question?

Thank you very much!

Nathalie
