Args | |
---|---|
initial_value
|
Initial value of the process. |
damping
|
The rate at which the noise trajectory is damped towards the mean. We must have 0 <= damping <= 1, where a value of 0 gives an undamped random walk and a value of 1 gives uncorrelated Gaussian noise. Hence in most applications a small non-zero value is appropriate. |
stddev
|
Standard deviation of the Gaussian component. |
seed
|
Seed for random number generation. |
scope
|
Scope of the variables. |
