Is there any other integration method in stan that can perform this integration apart from Runge-Kutta?
y = integrate_ode_rk45(sir, y0, t0, ts, theta, x_r, x_i)
Is there any other integration method in stan that can perform this integration apart from Runge-Kutta?

May I ask you to have a look at the manual?
Yes there are more choices.
In the manual, I only saw
ode_rk45(sho, y0, t0, ts, theta);
and
ode_bdf(sho, y0, t0, ts, theta); (for Stiff ODEs)
which I believe still uses the Runge-Kutta approach.
BDF is an implicit solver which uses Newton iterations. That is different from rk45. There is also an Adams-Moulton available.
Thank you.
