    An easy introduction to Regression in Data Analysis

    Learning and applying new methods and techniques can often be a daunting experience.

    This class is designed to provide you with a compact, and easy to understand, class that focuses on the basic principles of regression in data analysis.

    This class will focus on the understanding and applying linear regression in data analysis

    This class will explain what regression is and how Ordinary Least Squares (OLS) works. It will do this without any equations or mathematics. The focus of this class is on application and interpretation of regression in data analysis. The learning on this class is underpinned by many animated graphics that demonstrate particular concepts.

    No prior knowledge is necessary and this class is for anyone who would like to engage with quantitative analysis.

    The main learning outcomes are

    To learn and understand the basic intuition behind linear regression
    To be at ease with regression terminology
    To be able to comfortably interpret and analyze regression output
    To learn tips and tricks
    Specific topics that will be covered are

    What kinds of regression analyses exist
    Correlation versus causation
    Parametric and non-parametric methods
    The least squares method
    R-squared
    Beta's, standard errors
    T-statistics, p-values and confidence intervals
    Best Linear Unbiased Estimator
    The Gauss-Markov assumptions
    Bias versus efficiency
    Homoskedasticity
    Collinearity
    Functional form
    Zero conditional mean
    Regression in logs
    Practical model building
    Understanding regression output
    Presenting regression output
    The computer software Stata will be used to demonstrate practical examples.
