This function generatea a time series of one dimension Brownian motion, adapted from http://cos.name/wp-content/uploads/2008/12/stochastic-differential-equation-with-r.pdf .
1 |
x0 |
the start value, with the default value 0 |
t0 |
the start time point, with the default value 0 |
t |
the end time point, with the default value 1 |
n |
the number of points between t0 and t that will be generated, with the default value 100 |
1 2 3 4 |
Time Series:
Start = c(0, 1)
End = c(1, 1)
