    ML estimator of the coefficient of variation

    Hi guyz...
    I am reallllllly in need to solve this Q...

    Suppose ϴ is the model parameter, but we are interested in some function of ϴ. The invariance property of a ML estimator says that the ML estimator of g(ϴ) is just
    g(ɵ)^ = g(ɵ):

    Use this property to find the ML estimator of the coefficient of variation (σ/), where the data come from a Gaussian distribution with mean and variance σ ^2 .
