How to enter into Analytics Field
Let's start with Scope of Analytics

Scope of Analytics

The Advanced and Predictive Analytics (APA) software market is estimated to grow from $2.2B in 2013 to $3.4B in 2018, attaining a 9.9% CAGR in the forecast period. [IDC Report]. 

A top management consultancy firm, Mckinsey predicted shortage of analytics professionals in next 4-5 years.
"By 2018, the United States alone could face a shortage of 140,000 to 190,000 people with deep analytical skills as well as 1.5 million managers and analysts with the know-how to use the analysis of big data to make effective decisions".
Which software should i learn - SAS or R?

SAS

As per IDC survey, SAS is the top supplier, owning 35.4 percent market share of the 2013 advanced and predictive analytics market, more than twice that of the next-closest competitor. In addition, the IDC report ranked SAS among the top five providers with the highest growth rates in advanced and predictive analytics software.

SAS is an expensive tool but it is nothing to a bank or a drug company. Moreover, many companies have been using SAS for 30 years, and they have automated the whole process of analysis and have written millions of lines of working code. To convert all the stable reporting system from SAS to R, it may cost 50-100 times more.

SAS has outstanding support system. They provide tech support within few hours of raising a ticket.
SAS is the first choice for a large company especially BFSI (Banks,Financial Services and Insurance) and pharmaceutical companies as they can afford to invest that much in their reporting and analytics.

R
R is free. Anyone can download it. So far, it has been chosen by more than two million data scientists and statisticians around the world. R Studio and Revolution R software gives better interface to R functionality.

R creates awesome graphics. R is used frequently by The New York Times to create infographics and interactive data journalism applications.

R makes machine learning algorithms and text mining techniques so easy to implement in a predictive analytics project.
Because most cutting-edge research in statistics and machine learning is done in R, the latest techniques are usually available first as a package for R, years and years before they appear in other paid statistical packages.
R is the first choice for a start up and core data science company. It is mainly used in conjunction with SAS in most of the companies.

Summary : If you are a beginner to analytics world, you should learn SAS as there are more SAS jobs in the market as compared to R. If you know SAS already or you want to learn machine learning algorithms or text mining, you should learn R. In most of the large companies, SAS is a primary tool and R is a secondary tool mainly used for implementing text mining, graphics and machine learning algorithms.

    1. Thank you for writing to me. Yes, it all depends on the job profile. Still it's good to have basic knowledge of statistics even if you are not in statistical modeling profile. People who know statistics know how to generate insights from data in a computationally efficient and statistically effective manner.

    1. I apologize for the delayed response. In analytics, companies generally prefer professionals who have at least one year of experience in analytics field. Hence, there are a very few openings available for freshers. Most of the freshers working in analytics companies were hired from campus drive. Even if you are into different profile, I would suggest you to gain knowledge of SAS programming by practicing SAS coding in dummy datasets. This way, you will be able to crack SAS interviews and get a SAS profile. Also, you can test your knowledge on real world datasets that are listed in the article above and add to your CV.

    1. If you don't know basic concepts of statistics, you can learn these concepts. You have to decide whether you want to become a programmer or statistical analyst. Knowing SAS can help you fetch a SAS programmer profile. To crack interview for SAS Modeling profile, you have to learn basic and intermediate statistical concepts.

    1. Hadoop, Hive are big data tools. Knowing these tools would help you to get a big data developer role. To get into analytics, you need to learn practical application of SAS /R /Python. Once you are comfortable with any of these tools, you should focus on how to apply statistical techniques with these tools.

  18. Hi Deepanshu
    Great article I am curious to know if I do certification for Base SAS, what are the chances of getting into analytics field. I have 3 years of experience in IT industry.

    1. SAS Base certification alone will not help you land a job. At the end, you have to crack interview. To crack the interview, you need to have a good knowledge of how SAS is used in real time. But it's a good add-on to your CV.
