ECONOMETRICS: PS5 PROBLEM SET 5: ESTIMATION PROBLEMS 1 We have the following variables: Y: Food expenditure in USA. X: Family income. P: Price index. Two different regressions are estimated with the following estimation results (standard errors are in brackets): Coefficient for Regression X Y/P Y / X; P 0.112 (0.003) Coefficient for P 2.462 (0.407) -0.739 (0.114) Determination coefficient 0.614 0.978 Assuming that the true equation for Y includes both X and

Real World Quadratic Functions Maximum profit. A chain store manager has been told by the main office that daily profit‚ P‚ is related to the number of clerks working that day‚ x‚ according to the function P = −25x2 + 300x. What number of clerks will maximize the profit‚ and what is the maximum possible profit? In order to find the point at which profit is maximized‚ I must find the critical points of the first derivative of the equation. Coefficient of x^2 is negative‚ so

Appropriate question about relationship between variables posed. I am interested in investigating if there is any (meaningful) relationship between the Girth of the chest in inches and the weight of the bear in pounds. I am using chest as my explanatory variable and weight as response variable. The data source is from Pennsylvania Game Commission. I will use the relationship (if any) to predict the weight for a chest girth of 60 inches. Scatterplot drawn with the explanatory and response

Balancing Equations Balancing equations is a fundamental skill in Chemistry. Solving a system of linear equations is a fundamental skill in Algebra. Remarkably‚ these two field specialties are intrinsically and inherently linked. 2 + O2 ----> H2OA. This is not a difficult task and can easily be accomplished using some basic problem solving skills. In fact‚ what follows is a chemistry text’s explanation of the situation: Taken from: Chemistry Wilberham‚ Staley‚ Simpson‚ Matta Addison Wesley

Working with algebra you must understand why the properties of real numbers are so important. I will demonstrate my solutions to three problems and I will include my mathematical work. Also I will use five vocabulary words that help me find solutions to the problems. Properties of real numbers are useful for simplifying algebraic expression because a lot of thing we do in life are equations. We use a lot of mathematical terms in the real world. Lastly I will show every step I took to simplify and

Homework Sheet - Basic Algebra 1. John and Sarah are simplifying this expression. 3a + 8b + 7a – 6b John says the answer is 2a + 2b and Sarah says the answer is 10a + 14b. What is the correct answer? Sarah 2. Simplify these expressions. a) 4d + 6e – 2d – 3e = 2d-3e b) 12g – 3h – 8g + h = 4g-4h c) k + 2k + 3k – m – 2m – 3m = 6k-3m d) 7c + 4d – 10c + 5d = -3c+9d 3. Multiply out these brackets. a) 3(2a + 7) = 6a+21 b) 5(3x – 2y) = 15x-10 c) 2(4g2 – 3g) = 8g2-6
