18.440: Lecture 18 Uniform random variables

Uniform random variables and percentiles. Toss n = 300 million Americans into a hat and pull one out. uniformly at random. Is the height of the person you choose a uniform random variable? Maybe in an approximate sense? No. Is the percentile of the person I choose uniformly random? In. other words, let p be the fraction of people left in the hat

Chapter 2 The Maximum Likelihood Estimator

Example 2.2.1 (The uniform distribution) Consider the uniform distribution, which has the density f(x; )= 1I [0, ](x). Given the iid uniform random variables {X i} the likelihood (it is easier to study the likelihood rather than the log-likelihood) is L n(X n; )= 1 n Yn i=1 I [0, ](X i). Using L n(X n

6 Jointly continuous random variables

6.4 Function of two random variables Suppose X and Y are jointly continuous random variables. Let g(x,y) be a function from R2 to R. We define a new random variable by Z = g(X,Y). Recall that we have already seen how to compute the expected value of Z. In this section we will see how to compute the density of Z. The general strategy

Properties of Expected values and Variance

Another way to look at binomial random variables; Let X i be 1 if the ith trial is a success and 0 if a failure. Note that E(X i) = 0 q + 1 p = p. Our binomial variable (the number of successes) is X = X 1 + X 2 + X 3 + :::+ X n so E(X) = E(X 1) + E(X 2) + E(X 3) + :::+ E(X n) = np: What about products? Only works out well if the random ...

n iid random variables X k is the kth smallest X, usually called the kth order statistic.
