I'm interested in integrals of the form:
assume(N > 0) ;
assume(N > 1) ;
marginal : 'integrate((1/t-C)^(N-1)*exp(A-B/t^2),t,0,1/C) ;
Inspired by Jeffreys (1961, _Theory of Probability_, Oxford University
Press, p. 139), I thought a nice way forward would be to reduce this
to a finite series of incomplete Gamma functions, using the
but all I get when I issue this changevar command is the error
sign: sign of infinity is undefined.
-- an error. To debug this try: debugmode(true);
Any ideas, please?
