WebJul 6, 2015 · $\begingroup$ @Antoni Parellada Yes, i think you have translated my MATLAB code for the (a) correct way of doing it into Python numpy, complete with adjustment for np.linalg.cholesky being lower triangular vs. MATLAB's chol being upper triangular. WebThe correlation parameter ρ of the underlying bivariate normal determines this dependence. The conclusions drawn from the simulation could well depend on whether you generate X1 and X2 with dependence. The bivariate lognormal distribution is a simple solution in this case; it easily generalizes to higher dimensions in cases where the …
