Stability of a characterization of normal distributions based on the first two conditional moments
2000
International Journal of Mathematics and Mathematical Sciences
A characterization of normal distributions of two independent random variablesXandYwith a finiteE[X2]based on the linearity ofE[X|X+Y]and the homoscedasticity ofvar[X|X+Y]given by Rao (1976) is proved to be stable.
