# Thread: Maximum likelihodd estimators

1. ## Maximum likelihood estimators

I have two 2 dimension sets {x}1 and (x}2 where x is a vector.

My first question is the sets i have say {x}1 =
{
(0.555,2.601), ........}

Is this just x = 0.555 and y = - 2.601?
Assume that can both are drawn from 2-dim Gaussian distributions
with true means
μ1, μ2, and true covariance matrices 1 and 2respectively.

My next question is how do i find the maximum likelihood estimator for the true means and for the cobvariance matricies?
