  • Welcome

    - [Voiceover] Hi, I'm Wayne Winston. In this course I'll be showing you how to create and evaluate forecasts. We'll start by exploring the nature of time series data with scatter plots and moving average plots. Then we'll examine data bias and accuracy using methods including mean apps through deviation and sum of squared errors. Next we'll try out trend lines for forecasting. Then we'll model exponential growth, and compute CAGRs or compound annual growth rates. And finally, I'll help you understand seasonality of data and how to forecast with multiple regression. So roll up your sleeves and let's get ready to learn a lot about forecasting.
