Can I evaluate numerically the CDF of large number of variables with small number of different correlation coefficients(but, all nonzero)?
like more than 10000 random variables but less than 10 different correlation coefficients.
I tried NIntegrate[MultinormalDistribution[mean vector, Sigma matrix],integration range] with much less than 10000 number of RV's. But, what I got is "out of memory" message.
I just want to know whether I have to apply some approximations (which I have already) to reduce the number of variables, or there's a way to calculate it with Mathematica directly.
