A median of a random variable Y (or its distribution) is any value m such that P(Y ≤ m) ≥ ½ and P(Y ≥ m) ≥ ½.
(a) Show that the set of medians is a closed interval [m0, m1].
(b) Suppose that E|Y| < ∞.="" if="" c="" is="" not="" a="" median="" of="" y,="" show="" that="" e|y="" -="" c|="" ≥="" e|y="" -="" m|="" for="" any="" median="" m="" of="" y.="">
(c) Let X be a sample from Pθ, where θ ∈ Θ ⊂ R. Consider the estimation of θ under the absolute error loss function |a - θ|. Let Π be a given distribution on Θ with finite mean. Find the ℑ-Bayes rule w.r.t. Π, where ℑ is the class of all rules.

Figure out which year(s) sales persons' made more money by comparing the difference between 2012 to 2013, 2013-2014, and 2012-2014. Since each row belongs to a specific sales person, you need to do a specific analysis - what is it?
Suppose we fit the model y = X1β1+ ε when the true model is actually given by y = X1β2 + X2β2 + ε. For both models, assume E(ε) = 0 and Var(ε) = σ2I. where I is the identity matrix. Find the expected value and variance of the ordinary least-squares e..

A survey of the opinions of property owners about a street widening project was taken to determine whether the resulting opinion was related to the distance of front footage.
The following procedure aims at approximating the integral of g over the unit interval. Pick n points uniformly in the unit square
It is well known that similarity in attitudes, beliefs, and interests plays an important role in interpersonal attraction (see Byrne, 1971, for example). Thus, correlations for attitudes between married couples should be strong. Suppose a researcher ..
