Topic 15: Maximum Likelihood Estimation

Introduction to Statistical Methodology Maximum Likelihood Estimation Exercise 3. Check that this is a maximum. Thus, p^(x) = x: In this case the maximum likelihood estimator is also unbiased. Example 4 (Normal data). Maximum likelihood estimation can be applied to a vector valued parameter. For a simple

Joint and Marginal Distributions - University of Arizona

Joint and Marginal Distributions October 23, 2008 We will now consider more than one random variable at a time. As we shall see, developing the theory of multivariate distributions will allow us to consider situations that model the actual collection of data and form the foundation of inference based on those data. 1 Discrete Random Variables

random variable we want to compute the mean of is of the form f(X~) where X~ is a random vector. We will assume that the joint distribution of X~ is absolutely continous and let p(~x) be the density. (Everything we will do also works for the case where the random vector X~ is discrete.) So we focus on computing Ef(X~) = Z f(~x)p(~x)dx (6.1)

conditional distribution. But then his random sample has the same distri-bution as a random sample drawn from the population (with its unknown value of θ). So statistician B can use his random sample X0 1,···,X0 n to com-pute whatever statistician A computes using his random sample X1,···,Xn, and he will (on average) do as well as ...

The partition theorem says that if Bn is a partition of the sample space then E[X] = X n E[XjBn]P(Bn) Now suppose that X and Y are discrete RV’s. If y is in the range of Y then Y = y is a event with nonzero probability, so we can use it as the B in the above.

The muon is an elementary particle with an electric charge of 1 and a spin (an intrinsic angular momentum) of 1/2. It is an unstable subatomic particle with a mean lifetime of 2.2 µs. Muons have a mass of about 200 times the mass of an electron. Since the muon’s charge and spin are the same as the electron, a muon can be

Let f : (S,S) → (T,T ) be a function between measure spaces, then f is called measurable if f−1(B) ∈ S for every B ∈ T . (1.6) If (S,S) has a probability measure, then f is called a random variable.
