This short note gives an introduction to the Riemann-Stieltjes integral on R and Rn. Some natural and important applications in probability. Definitions. Riemann Stieltjes Integration. Existence and Integrability Criterion. References. Riemann Stieltjes Integration – Definition and. Existence of Integral. Note. In this section we define the Riemann-Stieltjes integral of function f with respect to function g. When g(x) = x, this reduces to the Riemann.

## Stieltjes Integral

In particular, no matter how ill-behaved the cumulative distribution function g of a random variable Xif the moment E X n exists, then it is equal to. Take a partition of the interval.

### Riemann–Stieltjes integral – Wikipedia

Thanks for confirming that this is true. Hildebrandt calls it the Pollard—Moore—Stieltjes integral.

### Stieltjes Integral — from Wolfram MathWorld The Stieltjes integral is syieltjes generalization of the Riemann integral. In particular, it does not work if the distribution of X is discrete i. I was looking for the proof.

Riemznn Stack Exchange works best with JavaScript enabled. If g is the cumulative probability distribution function of a random variable X that has a probability density function with respect to Lebesgue measureand f is any function for which the expected value E f X is finite, then the probability density function of X is the derivative of g and we have.

Rudinpages — AlRacoon 1 But this formula does not work if X does not have a probability density function with respect to Lebesgue measure. In mathematicsthe Riemann—Stieltjes integral is a generalization of the Riemann integralnamed after Bernhard Riemann and Thomas Joannes Stieltjes. Cambridge University Press, pp. Let me know if you spot any errors in it. I’ve supplied the proof for you now. Hints help you try stieltjees next step on your own.
