class: center, middle, inverse, title-slide # Welcome to Regression Analysis! ### Prof. Maria Tackett --- class: center, middle # Welcome! --- ### What is regression analysis? "In statistical modeling, regression analysis is a set of statistical processes for estimating the relationships among variables. It includes many techniques for modeling and analyzing several variables, when <font class="vocab">**the focus is on the relationship between a dependent variable and one or more independent variables (or 'predictors')**</font>. More specifically, regression analysis helps one understand how the typical value of the dependent variable (or 'criterion variable') changes when any one of the independent variables is varied, while the other independent variables are held fixed." .pull-right[ [-Wikipedia](https://en.wikipedia.org/wiki/Regression_analysis) ] --- ### You will learn... -- - How to apply methods for analyzing multivariate datasets, with an emphasis on interpretation -- - How to check whether a proposed statistical model is appropriate for the given data -- - How to address complex research questions using regression analysis -- - How to use R and Git to do statistical analysis in a reproducible way -- - The process for conducting data-driven research by applying the methods from this course to a long-term project --- ### Where to find information .vocab[Course website]: [sta210-fa20.netlify.app](https://sta210-fa20.netlify.app/) - Central hub for the course! .vocab[Sakai] - Gradebook - Class videos - Link to class meetings on Zoom .vocab[GitHub]: [https://github.com/sta210-fa20](https://github.com/sta210-fa20) - Assignment repos (we'll talk more about that later) --- ## Class meetings -- .vocab[Lecture] - Focus on concepts behind data analysis - Has two components: - **Lecture content videos** to watch before we meet - **Live lecture session** to ask questions and apply concepts from videos -- .vocab[Lab] - Focus on computing using R - Apply concepts from lecture to case study scenarios - Work on labs individually or in teams of 3 - 4 --- ## Activities and assessments -- - .vocab[Homework]: Individual assignments combining conceptual and computational skills. -- - .vocab[Labs]: Individual or team assignments focusing on computational skills. -- - .vocab[Quizzes]: Four quizzes to assess learning. -- - .vocab[Final Project]: Team project presented during the final exam period. -- - .vocab[Application Exercises]: Exercises worked on during the live lecture session. -- - .vocab[Statistics Experiences]: Engage with statistics outside of the classroom and reflect on your experience. --- ## Where to find help in the course -- - Attend .vocab[Office hours] to meet with a member of the teaching team. -- - Use .vocab[Piazza] for general questions about course content and/or assignments, since other students may benefit from the response. -- - Use email for questions regarding personal matters and/or grades. --- ## Academic Resource Center The [Academic Resource Center (ARC)](https://arc.duke.edu/) offers free services to all students during their undergraduate careers at Duke.
