About Forecasting Certification Training

Early knowledge is the wealth, even if that knowledge is bit imperfect!!! Wouldn’t you want to unlock the mystery of predicting the stock market? And many of us want to understand how companies are managing their inventory and other resources by forecasting their sales.

Here is the solution in the form forecasting technique also called as time series analysis. Forecasting techniques will be applied for time series data. Forecasting Analytics is considered as one of the major branches in big data analytics.

Managers often have to take decisions in uncertain environment and often find themselves in a bad situation due to lack of skills on applying the right analytical techniques on the data. Forecasting techniques helps companies save millions of dollars by adjusting their production schedules and other plans. Forecasting techniques on univariate and multivariate time series analysishave huge applications across the industries and areas such as Operations management, Finance & Risk management, Retails, Telecom and manufacturing.

Moving Averages and smoothing methods, Box- Jenkins (ARIMA) methodology, Regression with time series data, Holts-Winter, Arch-Garch and Neural Network are the methods widely used for forecasting. Arch-Garch and Neural Networks are the advanced techniques in the forecasting analytics which will be used to model the high frequency data such as stock market and big data.

FAQs

  • Forecasting is predicting the future by considering the historical past data. For e.g., companies forecast sales of next quarter by looking into sales of previous quarters. However, data should be in time-series for forecasting the future events.
  • Data arranged in a sequence in an order based on time. For e.g., company sales should be arranged in a time sequence (Jan ‘15, Feb ‘15, March ‘15, April ‘15, May ‘15, June ‘15, July ’15) before forecasting the sales of Aug ’15.
  • Forecasting is used across all industries & sectors. Majorly it is applicable for Financial services & insurance, Retail & in weather forecasting.
  • A lot of tools are used including R, SAS, STATA, MATLAB, Minitab, Excel etc. We at ExcelR teach you forecasting on R which is highly in demand.
  • The detailed course outline is provided on the website. All the forecasting models including AR, MA, ARMA, ARIMA, ARCH & GARCH models are taught.
  • Yes, forecasting techniques are imperative for one to be a successful data scientist.
