As the title says, I wonder if it is possible to calculate a Lebesgue integral in MathematicaMathematica, especially when the domain of integration is $$\mathbb{R}^N$$, or in other words multivatiate Lebesgue integration is of interest. As an example, one could take $$f_0$$ and $$f_1$$ as two different (possibly correlated) bi-variate Gaussian density functions and consider

$$\int_{\frac{f_1}{f_0}>\tau}f_0\mbox{d}\mu=\int_{\Large\{x,y:\frac{f_1(x,y)}{f_0(x,y)}>\tau\Large\}}f_0(x,y)\mbox{d}x\mbox{d}y$$ for some known number $$\tau$$.

If it is not possible can one manipulate the existent functions of MathematicaMathematica to get a method which can calcuate the Lebesgue integral. I am only interested in very fast numerical methods, no analytical results are needed.

Thank you very much.

(iiii) I have no idea how I can do it in Mathematica
