摘要：
By studying uniqueness, we show that Pearson's method of moments for mixtures of two normal distributions must be completed. We then invert a second set of moment equations, which is constructed to complete the classical system of moments. We are thus able to stabilize the method. To cite this article: E. Monfrini, C R.
