From stock prices to climate data, time series data are found in a wide variety of domains, and being able to effectively work with such data is an increasingly important skill for data scientists. This course will introduce you to time series analysis in Python. After learning about what a time series is, you'll learn about several time series models ranging from autoregressive and moving average models to cointegration models. Along the way, you'll learn how to estimate, forecast, and simulate these models using statistical libraries in Python.

Across industries, time series data, which is any information collected over a regular interval of time, is used by organisations. Just a few examples are daily stock prices, energy consumption rates, social media engagement metrics, and retail demand. Time series data analysis exposes trends, seasonal patterns, and future event forecasts, all of which can assist you in making money. Companies can, for example, use seasonal fluctuations in demand for retail products to plan promotions to maximise sales throughout the year.
A time series is a collection of observations made at regular intervals over time. A time series might be hourly, daily, weekly, monthly, quarterly, or annual, depending on the frequency of observations. You may also have seconds and minute-by-second time series, such as the number of clicks and user visits each minute, etc. Why bother analysing a time series in the first place? Because it is the first step in the process of developing a series forecast. Furthermore, time series forecasting has huge economic significance because crucial company data such as demand and sales, number of website visitors, stock price, and so on are all time series data.
When analyzing time series data, you should undertake a number of steps. First, you need to check for stationarity and autocorrelation. Stationarity is a way to measure if the data has structural patterns like seasonal trends. Autocorrelation occurs when future values in a time series linearly depend on past values. You can just enroll yourself in the complete data analysis program offered by DataTrained which will teach you major concepts and help you develop a strong base in this domain.
Almost every data scientist will have to perform time series data analysis at some point in their career. Data scientists can find trends, foresee events, and so guide decision-making by having a good understanding of the tools and methodologies for analysis. Understanding seasonality trends using stationarity, autocorrelation, and trend decomposition can help organisations schedule promotions throughout the year, increasing revenues. Finally, time series forecasting is a powerful tool for predicting future events in time series data, which can have a big impact on decision-making. These types of studies are crucial for any data scientist or data science team looking to use time series data to provide value to their firm. This post's code is accessible on GitHub.
Organizations employ time series data, which is any information collected over a regular interval of time, in their operations across industries. Daily stock prices, energy consumption rates, social media engagement measures, and retail demand are just a few of the examples. Analyzing time series data reveals trends, seasonal patterns, and forecasts for future events, all of which can help you make money. Companies can, for example, arrange promotions to maximise sales throughout the year by knowing seasonal changes in demand for retail products.
Finally, forecasting helps you to predict future events, which can help you make better decisions. For time series forecasting, you can use a variety of strategies, but we'll focus on the autoregressive integrated moving average (ARIMA).
Time series analysis also suffers from a number of weaknesses, including problems with generalization from a single study, difficulty in obtaining appropriate measures, and problems with accurately identifying the correct model to represent the data.

The central point that differentiates time series problems from most other statistical problems is that in a time series, observations are not mutually independent. Rather a single chance event may affect all later data points. This makes time series analysis quite different from most other areas of statistics.
Due to the vast creation of time series data, time series data analysis and forecasting have become increasingly vital, and as continuous monitoring and gathering of such data grows more widespread, the demand for more efficient analysis and forecasting will only grow. As a leading expert in the field of time series analysis and forecasting.
Given current and historical data, time series analysis allows us to forecast future values in a time series. To forecast the amount of travellers, we'll use the ARIMA approach. ARIMA allows us to forecast future values by combining historical values in a linear fashion. We'll use the auto arima package, which will save us time by removing the need for hyperparameter adjustment.
Yet, analysis of time series data presents some of the most difficult analytical challenges: you typically have the least amount of data to work with, while needing to inform some of the most important decisions. Contiguous observations are common in time series problems, such as one per hour, day, month, or year. A discontiguous time series is one in which the observations are not uniform throughout time. Missing or faulty values may be the source of the observations' lack of regularity. Apart from all that DataTrained’s Time Analysis course can help you learn everything from scratch to advanced level.
Your main focus will be on developing predictive models for critical planning entities; analyzing large amounts of data to identify and evaluate opportunities to improve customer experience, network speed, cost and efficiency; and presenting the results to non-technical audiences with the aid of visualization tools. You will identify effective metrics to quantify the improvements resulting from the application of your developed tools and you will evaluate the trade-offs between potentially competing objectives.
The ideal candidate will demonstrate deep understanding of statistical and machine learning concepts, technical skills for leveraging analytical tools to solve large scale problems and aptitude to remain abreast with data science related technologies. The successful candidate will have good communication skills and ability to speak at a level appropriate for the audience; will collaborate effectively with fellow scientists, data/software engineers, and product/program managers; and will deliver business value in a close partnership with many stakeholders from operations, finance and software-engineering.
