What is Time Series Analysis?

‘Time’ is the most important factor which ensures success in a business. It’s difficult to keep up with the pace of time.  But, technology has developed some powerful methods using which we can ‘see things’ ahead of time!

Nope, not the time machine, we are talking about the methods of prediction & forecasting. As the name ‘time series forecasting’ suggests, it involves working on time (years, days, hours, minutes) based data, to derive hidden insights to make informed decision making.

Importance of Time Series Analysis

Time series models are very useful models when you have serially correlated data as shown above. Most businesses work on time series data to analyze

• Sales numbers for the next year

• Website Traffic

• Competition Position

• Demand of products

• Stock Market Analysis

• Census Analysis

• Budgetary Analysis

This is just the tip of the iceberg and there are numerous prediction problems that involve a time component and concepts of time series analysis come into picture.

Why is Time Series Forecasting Challenging?

But what makes a time series more challenging than say a regular regression problem? There are 2 things:

• Time Dependence of a time series - The basic assumption of a linear regression model that the observations are independent doesn’t hold in this case.
• Seasonality in a time series - Along with an increasing or decreasing trend, most time series have some form of seasonal trends, i.e. variations specific to a particular time frame.

The above challenges motivated us to build a hands on course explaining the implementation of various time series forecasting methods using Python

What do I need to start Time Series Forecasting course?

• A working laptop / desktop with 4 GB RAM
• A working Internet connection
• Basic knowledge of Machine Learning
• Basic knowledge of Python - check out this Course
• first, if you are new to Python
• Python libraries you need for completing the time series forecasting project: sklearn, pandas, statsmodels

This is all it takes for you to take your first step with Time Series forecasting using Python.

Project: Time Series Forecasting

Unicorn Investors wants to make an investment in a new form of transportation - JetRail. JetRail uses Jet propulsion technology to run rails and move people at a high speed! The investment would only make sense if they can get more than 1 Million monthly users within the next 18 months. In order to help Unicorn Ventures in their decision, you need to forecast the traffic on JetRail for the next 7 months. You are provided with traffic data of JetRail since inception in the test file.

What do you get as a part of the Time Series Forecasting using Python course?

This course is divided into 3 sections:

• Understanding Time Series Analysis
• Data Exploration for Time Series
• Time Series Forecasting using different methods

These sections are supplemented with theory, coding examples and exercises. Additionally, you will be provided with the below resources:

• Time Series Datasets  Dataset from a real-life industry time series use case
• Jupyter Notebooks  Fully functioning Python codes for understanding the data and later building models for performing time series forecasting
