I don't want to specify the functions and limits each time I change K. nquad(integrand, [bounds_a(), bounds_x()], args = (t_est))[0] But from what I understand of the documentation on nquad, what I have written in this line corresponds exactly to 3 arguments: a and x, implicit in giving their limits, and t_est, a vector. Where one or both limits for the nquad functions is a formula the limits are entered in one cell in the format: [lower limit or function, upper limit or function]. Integration problems are common in statistics whenever we are dealing with continuous distributions. One might think that the test in the question is an appropriate one if multi-dimensional integration is done by the integrator in a recursive manner. The order of integration (and therefore the bounds) is from the innermost integral to the outermost one.
