The Euler scheme problem
I got a problem about the computation of the Euler scheme, e.g. in GCFM model, the equation is
if I use the v(t) instead R(t) in the first equation, does this turn to be a first order ODE? and I think Euler scheme is using to solve the first order ODE, and How to using it to solve the second order ODE. Is there a derivation about how to using Euler scheme solve the first equation? Thank you!
