Time Series Analysis

Predict future trends from historical data. Master ARIMA models, seasonality detection, and forecasting techniques using Python statsmodels.

Time is the most critical dimension in business data. This course teaches you to analyze data that changes over time to predict future outcomes. You will learn to decompose time series into trend, seasonality, and noise components. Master statistical models like ARIMA and SARIMA for rigorous forecasting, and explore modern libraries like Prophet. Whether predicting stock prices, website traffic, or retail sales, these skills enable you to answer the question 'what happens next?' with statistical confidence.
