APPLIED BUSINESS STATISTICS

Kevyn Stefanelli

Instructional goals

By the end of this course, students will be able to: 1. Understand and apply basic statistical concepts and principles to business problems. 2. Exploit regression analysis to analyze and interpret data in a business context. 2. Understand, use and interpret simple, multiple, logistic, and panel regression. Use the R programming language to perform data analysis.

Intended learning outcomes

Understand the basic principles of applied business statistics and how they are used to make decisions in a variety of business settings. Apply techniques of regression analysis to quantify the relationships between variables and make predictions based on data. Understand the principles of factor analysis as a method of data reduction and variable selection (intro). Apply logistic regression analysis to make predictions based on binary outcomes, such as yes/no decisions (intro). Understand the principles of panel data analysis and how it can be used to analyze data collected over time and across entities (intro). Develop proficiency in using R or other statistical software packages to analyze and interpret data. Communicate effectively about statistical analyses and their results, both in writing and in oral presentations. Think statistically. By the end of the course, students should be able to use these techniques to analyze real-world data, draw appropriate conclusions, and communicate their findings effectively to others.

Prerequisites

Completion of an introductory course in statistics, covering basic concepts of probability, descriptive statistics, hypothesis testing, and simple linear regression. Familiarity with basic algebra and calculus concepts, including functions, derivatives, and integrals (I want to stress basic). Basic knowledge of computer programming, including familiarity with R or another statistical software package. These prerequisites are intended to ensure that students have a solid foundation in the concepts and tools necessary to succeed in the course. At the beginning of the course we will review briefly all these topics.

Course Contents

Topics may undergo changes 1. Probability and Statistics Review Basic concepts of probability and statistics Probability distributions and their properties Confidence Interval and hypothesis tests 2. Simple Linear Regression Intro to simple linear regression Estimating the regression parameters Evaluating the goodness of fit Making predictions and inferences 3. Multiple Linear Regression Intro to multiple linear regression Estimating the regression parameters Evaluating the goodness of fit Making predictions and inferences 4. Introduction to Factor Analysis How factor analysis can be used as a method for data reduction Exploratory and confirmatory factor analysis Interpreting factor loadings Using factor analysis for dimension reduction and variable selection 5. Logistic Regression: pills Logistic regression to say "yes" or "no" Examples of logistic regression in business settings Interpreting logistic regression coefficients The logistic regression in the decision-making process 6. Panel Data Analysis Intro to panel data analysis Estimating the panel regression equation and its coefficients (only Fixed Effects) Making predictions and inferences Each week, we use the statistical software R to analyze topics covered in class that week. Data visualization will play a key role in this course.
