Chi2rvs. Tuple of ints optional shape or random variates. The standard definition of the noncentral chi-squared distribution is that it is the sum of the squares of normal variates that.
Continuous random variables are defined from a standard form and may require some shape parameters to complete its specification. By intuition I know that the higher the degrees of freedom parameter the more the t copula should resemble the Gaussian one and hence the lower the tail dependency.

SUM OF CHI-SQUARE RANDOM VARIABLES Define the RV Z2 -Y.
Lower and upper tail probability x. Tuple of ints optional shape or random variates. Continuous random variables are defined from a standard form and may require some shape parameters to complete its specification. S chi2rvs df sizen_samples npnewaxis Otherwise the variable s is just a single constant and your X ends up being a sample from the multivariate normal scaled by npsqrt dfs rather than the t-distrubution that you need.
