SummaryIn a mixture ofknormal distributions the maximum likelihood estimates of μjand σ2j, forj= 1, …,k, can be expressed by a weighted sample mean and a weighted sample variance, and the maximum likelihood estimates of the over-all mean and variance of the mixture coincide with the sample mean and sample variance.
