Review: Central Limit Theorem

1 point possible (graded)

The Central Limit Theorem states that if X1,…,Xn are i.i.d. and

E[X1]=μ<∞ ; Var(X1)=σ2<∞,

then

n−−√[(1n∑i=1nXi)−μ]−→−−n→∞(d)Wwhere W∼N(0,?).

What is Var(W)? (Express your answer in terms of n, μ and σ).

What is wrong with the following statement of the central limit theorem? Central Limit Theorem.  If the random variables X1, X2, X3, …, Xn are a random sample of size n from any distribution with finite mean μ and variance σ2, then the distribution of will be approximately normal, with a standard deviation of σ / √n.

Review: Manipulating Multivariate Gaussians 1 point possible (graded) Recall that a multivariate Gaussian N(μ⃗ ,Σ) is a random vector Z=[Z(1),…,Z(n)]T where Z(1),…,Z(n) are jointly Gaussian , meaning that the density of Z is given by the joint pdf f:Rn → R Z ↦ 1(2π)n/2det(Σ)−−−−−−√exp(−12(Z−μ⃗ )TΣ−1(Z−μ⃗ )) where μ⃗ i =E[Z(i)],(vector mean).

Confidence interval Concept Check 1 point possible (graded) As in the previous section, let X1,…,Xn∼iidexp(λ). Let λˆn:=n∑ni=1Xi denote an estimator for λ. We know by now that λˆn is a consistent and asymptotically normal estimator for λ. Recall qα/2 denote the 1−α/2 quantile of a standard Gaussian. By the Delta method: λ∈[λˆn−qα/2λn−−√,λˆn+qα/2λn−−√]=:I with probability 1−α. However, I is still not a confidence interval for λ. Why is this the case?

Method of Moments Concept Question II 1 point possible (graded) Let (E,{Pθ}θ∈Θ) denote a statistical model associated to a statistical experiment X1,…,Xn∼iidPθ∗ where θ∗∈Θ is the true parameter. Assume that Θ⊂Rd for some d≥1. Let mk(θ):=E[Xk] where X∼Pθ. mk(θ) is referred to as the k-th moment of Pθ . Also define the moments map: ψ:Θ →Rd θ ↦(m1(θ),m2(θ),…,md(θ)). What conditions on ψ do we have to assume so that the method of moments produces a consistent and asymptotically normal estimator?...

The weak law of large numbers states that the mean of a sample is a consistent estimator of the mean of the population. That is, as we increase the sample size, the mean of the sample converges in probability to the expected value of the distribution that the data comes from, provided that expected value is finite. Consider a numerical example, a Student t distribution with n = 5, the same as we have already seen earlier in this module....

Reconsider the game of roulette. Recall that when you bet $1 on a color, you have an 18/38 probability of winning $1 and a 20/38 probability of losing $1 (for a net winnings of -$1). Consider playing for a random sample of n = 4 spins, and consider the statistic x-bar = sample mean of your net winnings per spin. a) Determine the (exact) sampling distribution of x-bar. [Hint: Start by listing the possible values of x-bar. Then use the...
