正在犹豫这个换行值不值得。DC同类职位，像我这个背景，Salary大概在那个范围？ |

知道y0和zL
不知道z0
能用Runge Kutta方法吗？
y方程向前走的时候，需要用到z0，而z0需要z方程倒退到最后才能知道。
如果z方程倒退的话，好像也要用到YL才行，y方程还没解哪能得到YL阿。
这个方程能simulation出来吗？具体应该怎么算呢？请大侠们帮帮忙！ |

a random field( process) w(x), x \in (0, pi).
The mean is zero everywhere.
Covariance function c(x1,x2) = exp(-|x1-x2|/b ), b>0
We also know the PDF of w(x) for any fixed x.
How to do the simulation?
2) simplified(approximated) version:
Use Karhunen-Loeve expansion of w(x), to obtain an approximation:
w(x) = f(x) alpha1 + g(x) alpha2
then both alpha1 and alpha2 have the given PDF, and are uncorrelated.

发帖数: 1437 | 32 For a set of stochastic ODE
dX/dt = A*X + F*e,
where e is white noise with known variance and mean
I know how to do without noise term. But with the noise term, what is the
most common way to do the simulation? Generate a bunch of random numbers first
then add them in one by one? Or a more "educated" method than this?

actually X is a set of variables. Here I am sovling a stochastic ODEs, not
just one.
Let me flip coin for the question: I have raw time series for a bunch of
variables. Someone said they all can be well simulated using stochastic ODEs.
So he goes ahead and use dX/dt = A*X + F*e to fit my time series. Now if I
wanna test how good such stochastic ODEs can predict future time series, which
way is the most effective way to tell?
Thanks. :-)
