Descriptive Statistics and Probability Distribution Problem Sets Emily Noah QNT561 Anthony Matias December 24‚ 2012 Descriptive Statistics and Probability Distribution Problems Sets Descriptive statistics and probability distribution is two ways to find information with certain data giving. In Descriptive statistics the data can give a mode‚ mean‚ median‚ and range by the numerical information‚ which is giving to find the information. In probability distribution the data is collected and

Gauss Markov Theorem In the mode [pic]is such that the following two conditions on the random vector [pic]are met: 1. [pic] 2. [pic] the best (minimum variance) linear (linear functions of the [pic]) unbiased estimator of [pic]is given by least squares estimator; that is‚ [pic]is the best linear unbiased estimator (BLUE) of [pic]. Proof: Let [pic]be any [pic]constant matrix and let [pic]; [pic] is a general linear function of [pic]‚ which we shall take as an estimator of [pic]. We must specify

Economics 370 Microeconomic Theory Problem Set 6 Answer Key 1) Describe the effects on output and welfare if the government regulates a monopoly so that it may not charge a price above p‚ which lies between the unregulated monopoly price and the optimally regulate price (determined by the intersection of the firm’s marginal cost and the market demand curve). As usual‚ the monopoly determines its optimal output on the basis of MR = MC. Here‚ however‚ it cannot charge a price in excess of p*. So

Managerial Finance – Problem Review Set – Capital Structure and Leverage 1) If a firm utilizes debt financing‚ an X% decline in earnings before interest and taxes (EBIT) will result in a decline in earnings per share that is larger than X. a.

Vandenberghe January 4‚ 2006 Chapter 2 Convex sets Exercises Exercises Definition of convexity 2.1 Let C ⊆ Rn be a convex set‚ with x1 ‚ . . . ‚ xk ∈ C‚ and let θ1 ‚ . . . ‚ θk ∈ R satisfy θi ≥ 0‚ θ1 + · · · + θk = 1. Show that θ1 x1 + · · · + θk xk ∈ C. (The definition of convexity is that this holds for k = 2; you must show it for arbitrary k.) Hint. Use induction on k. Solution. This is readily shown by induction from the definition of convex set. We illustrate the idea for k = 3‚ leaving the

Should Highway Speed Limits Be Increased? Should highway speed limits be increased? Should we strike down every sign that the government posts and uses to regulate the speed limit on the thousands of highways around the country? Should we trust the driving ability of each and every person to drive within a reasonably safe speed? The response that most people lean toward is one of negativity. People automatically assume that the speeds presently posted on our highways are there only for our
