This document provides a step-by-step guide for creating a multivariate linear regression model using Excel. The underlying principle of this technique is called the least-squared, which is the process of minimizing the distance between the predicted value of an observation and the actual value of that observation. Linear regression is a statistical technique used to observe trends, determine correlation, and predict future observations.

Completion of this course will give you an understanding of the concepts of the Bayesian approach, understanding the key differences between Bayesian and Frequentist approaches, and the ability to do basic data analyses.These instructions read better in this Linear Regression Excel Directions PDF file Linear Regression in Excel Introduction The lectures provide some of the basic mathematical development as well as explanations of philosophy and interpretation. For computing, you have the choice of using Microsoft Excel or the open-source, freely available statistical package R, with equivalent content for both options. This course combines lecture videos, computer demonstrations, readings, exercises, and discussion boards to create an active learning experience. In particular, the Bayesian approach allows for better accounting of uncertainty, results that have more intuitive and interpretable meaning, and more explicit statements of assumptions. We will compare the Bayesian approach to the more commonly-taught Frequentist approach, and see some of the benefits of the Bayesian approach. We will learn about the philosophy of the Bayesian approach as well as how to implement it for common types of data. This course introduces the Bayesian approach to statistics, starting with the concept of probability and moving to the analysis of data.
