Time series analysis is the art of extracting meaningful insights and revealing patterns from time series data using statistical and data visualization approaches. These insights and patterns can then be utilized to explore past events and forecast future values in the series.
This book goes through all the steps of the time series analysis process, from getting the raw data, to building a forecasting model using R. You will learn how to use tools from packages such as stats, lubridate, xts, and zoo to clean and reformat your raw data into structural time series data. As you make your way through Hands-On Time Series Analysis with R, you will analyze data and extract meaningful information from it using both descriptive statistics and rich data visualization tools in R, such as the TSstudio, plotly, and ggplot2 packages. The latter part of the book delves into traditional forecasting models such as time series regression models, exponential smoothing, and autoregressive integrated moving average (ARIMA) models using the forecast package. Last but not least, you will learn how to utilize machine learning models such as Random Forest and Gradient Boosting Machine to forecast time series data with the h2o package.
