Class Dates: 8/29/2015, 9/12/2015, 9/26/2015, and 10/10/2015 Make-up Date 10/17/2015 Course Description: This computer-based course builds students’ skills to empirically analyze economic and financial data and conduct financial forecasting. The course introduces students to model building and estimation. The course covers single and multiple linear and nonlinear regressions, time series analysis and forecasting. Prerequisite: BUS 598 (Quantitative Foundations and Business Applications) or equivalent. Econometrics Syllabus Dr. F. Raouf Page 1 of 4 Learning Goals: 1. Students will demonstrate how to test a hypothesis and construct a confidence interval for any population mean(s). 2. Students will estimate simple and multiple linear regressions, test a hypothesis, and construct a confidence interval. 3. Students will construct a nonlinear regression, transfer it into a linear regression, and then estimate it. 4. Students will identify the violations of the classical OLS assumptions and formulate a solution to fix them. 5. Students will develop an understanding of different forecasting methods, how to apply them to time series data, and predict the future values for these time series. 6. Students will perform a regression analysis using Excel. Method of Instruction: The instructor is planning to conduct this course as follows: Lectures: Fully explain the materials covered with several real world examples to clarify the materials. Applications: Help students apply and understand the topics covered. Course Requirements: Final Course Project (Tuesday October 14, 2015) Assignments and Case Studies Method of Evaluation: Final project counts 50% of the grade. Assignments and case studies count 50% of the grade. Note the Following: Extension for the final project will be given in real emergency only. All assignments and case studies are to be submitted electronically via: 1. Campus Web or 2. Email attachment All assignments are due by the end of the day Saturday following the class meeting. Late assignments are penalized by taking one point off the grade. Assignments are not accepted after the answer is already posted on Campus Web. Grade for the course is based on curving the total course grade for students at the end of the semester. The grade distribution will then be compared to the College’s grading scale. The student will be granted the higher of the two grades. Goldey-Beacom College grading scale is A+ 95-100 B 80-84.9 A 90-94.9 C+ 75-79.9 B+ 85-89.9 C 70-74.9 Students are expected to attend all classes, to be in class on time, to stay in class until the end of the class, not to interrupt the class in any way, and to participate in class discussion. This course is governed by the Academic Honor Code and the Respectful Learning Environment Policy of the College. Any violation of this policy will be penalized.
