WebJan 1, 2015 · 15. If you just want correlation through a Gaussian Copula (*), then it can be calculated in a few steps with numpy and scipy. create multivariate random variables with desired covariance, numpy.random.multivariate_normal, and creating a (nobs by k_variables) array. apply scipy.stats.norm.cdf to transform normal to uniform random … WebApr 16, 2013 · you could choose the covariance matrix to be. cov = [ [1, 0.2], [0.2, 1]] This makes the cov (X,Y) = 0.2, and the variances, var (X) and var (Y) both equal to 1. So rho would equal 0.2. For example, below we generate pairs of correlated series, X and Y, 1000 times. Then we plot a histogram of the correlation coefficients:
