difference between observed sufficient statistics which statement to use for maximum likelihood estimation? what is the difference between observed sufficient and expected sufficient statistics average vs expected sufficient statistics what is considered expected statistics in exponential family exponential family definition exponential family maximum likelihood expected sufficient or observed sufficient statistics expected sufficient statistic what is the difference between an observed sufficient and an expected sufficient statistic what is meant by expected sufficient statistics in exponential family exponential family - expected sufficient statistics exponential family maximum likelihood estimation exponential family definition why are expected sufficient statistics equal to observed sufficient? exponential family definition why are observed sufficient statistical results greater than expected sufficient statistics exponential family meaning what is expected sufficient vs. expected sufficient what is the difference between expected sufficient and observed sufficient statistics?
