Mark the incorrect statement(s): O Independent and identically distributed random variables are not necessary for getting maximum likelihood estimators. O Maximum likelihood estimation can always be found analytically for any kind of distribution. O The maximizer values of the estimators of the likelihood function are the same maximizers of the log- likelihood function. () Method of moments allows us to estimate n parameters by solving a system of equations of the n population moments (mean, variance, .n'-moment) equal to the n corresponding sample moments
