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 40 lectures and 6.5 hours of content. It's designed for all forecasting models knowledge levels and a basic understanding of R statistical software is useful but not required.

At first, you'll learn how to read data files and perform statistical computing operations by inputting instructions from R script files in the RGui console. Next, you'll estimate simple forecasting methods such as arithmetic mean, naïve or random walk, seasonal random walk, random walk with drift and use them as benchmarks against other more complex ones. After that, you'll evaluate these methods' forecasting accuracy through mean absolute error, root mean squared error and mean absolute percentage error metrics.

Then, you'll identify time series level, trend and seasonality patterns through simple moving averages together with Brown's, Holt's, Gardner's, Taylor's and Winter's exponential smoothing (ETS) methods. Next, you'll automatically select best method by comparing several information loss criteria and evaluate these methods' forecasting accuracy through previously studied error metrics and the introduction of Hyndman and Koehler's mean absolute scaled error.

After that, you'll evaluate if time series is first order trend stationary with augmented Dickey-Fuller and Kwiatkowski-Phillips-Schmidt-Shin tests. 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 and partial autocorrelation functions. Later, you'll automatically select best model by comparing Akaike's and Schwarz's Bayesian information loss criteria and evaluate these models' forecasting accuracy through previously studied errors metrics. Finally, you'll value if best model's forecasting errors are white noise with Ljung-Box lagged autocorrelation test and therefore don't include any predicting information.
