No. You are confusing the mixture distribution and the summation of distributions. w 1 N + w 2 M (no constraint is required on w) is a random variable and is dependent on the covariance between N, M. On the other hand, the mixture distribution describes a CDF F X such that. F X ( x) = w 1 F N ( x) + w 2 F M ( x) WebThe formula for the cumulative distribution function of the standard normal distribution is $ F(x) = \int_{-\infty}^{x} \frac{e^{-x^{2}/2}} {\sqrt{2\pi}} $ Note that this integral does not exist in a simple closed formula. It is computed numerically. The following is the plot of the normal cumulative distribution function.
