Cvar Kolmogorov-Smirnov Distance from a Discrete Distribution to a Mixture of Normal Independent Distributions (ksm_cvar_ni)

Cvar Kolmogorov-Smirnov Distance from a Discrete Distribution to a Mixture of Normal Independent Distributions. CVaR Kolmogorov-Smirnov distance between a mixture of normal distributions with variable coefficients and a fixed discrete distribution  (as function of variable coefficients). This distance is calculated by taking CVaR of absolute values of differences between two distributions at atoms of the fixed discrete distribution.
