Become a Forecasting Models Expert and Put Your Knowledge in Practice

Learning forecasting methods and models is indispensable for business or financial analysts in areas such as sales and financial forecasting, inventory optimization, demand and operations planning, and cash flow management. It is also essential for academic careers in data science, applied statistics, operations research, economics, econometrics and quantitative finance. And it is necessary for any business forecasting related decision.

But as learning curve can become steep as complexity grows, this course helps by leading you through step by step real world practical examples for greater effectiveness.

Content and Overview

This practical course contains 43 lectures and 8.5 hours of content. It's designed for all forecasting models knowledge levels and a basic understanding of Excel is recommended.

At first, you'll estimate simple forecasting methods such as naïve or random walk and use them as benchmarks against other more complex ones.

Then, you'll identify time series level, trend and seasonality patterns through simple and weighted moving averages together with Brown's, Holt's, Gardner's, Taylor's and Winter's exponential smoothing (ETS) methods. Next, you'll select best methods by comparing scale-dependent and scale-independent forecasting errors' metrics such as Hyndman and Koehler's mean absolute scaled error.

After that, you'll evaluate if time series is first order stationary with deterministic trend and seasonality together with augmented Dickey-Fuller test. Next, you'll calculate time series conditional mean with Box-Jenkins's autoregressive integrated moving average (ARIMA) models. Then, you'll determine models' parameters with autocorrelation, partial autocorrelation functions and use them to evaluate if forecasting residuals are white noise together with Ljung-Box test. And then, you'll choose best models by comparing Akaike's and Schwarz's Bayesian information criteria.

Finally, you'll test forecasting accuracy of methods and models by comparing their predicting capabilities.
