  • Vectorizing a random walk ensemble generator in RFebruary 17

    This R script generates ensembles of random walks. The random walks are all expressed as values from function f(t) = alpha * f(t-0) + epsilon, where epsilon is a random number from a normal distribution. The final result is a list of ensembles genera

    Python: random walk (1D) with exponentially distributed jump distanceFebruary 13

    For fixed jump distance I have import scipy as sp import numpy as np from numpy.random import * from pylab import * fwd = 0.5 #Probability to move forward bwd = 1 - fwd #Probability to move backwards N = 100 #Number of Steps d_avg = 0 time = np.arang
