Learn how to use Python for data science from Edvancer.Cost and ease of learning SAS is an expensive commercial software and is mostly used by large corporations with huge budgets. Python and R are free software that can be downloaded by anyone. You don’t require prior knowledge in programming to learn SAS, and its easy-to-use GUI makes it the easiest to learn of all the three. The ability to parse SQL codes, combined with macros and other native packages make learning SAS child’s play for professionals with basic SQL knowledge. To analyze data in Python, you will use data mining libraries like Pandas, Numpy, and Scipy. In other words, you won’t code in native Python language when analyzing data. The code you write in these libraries looks somewhat similar to the code you write in R. Hence, it is easier to learn Python for data science when you are already familiar with R. If you already know R, then you should learn the basics of Python programming language before you start to learn the Python data mining ecosystem. So, don’t think that R is difficult, and Python is easy to learn! Data Science capabilities SAS is extremely efficient at sequential data access, and database access through SQL is well integrated. The drag-and-drop interface makes it easy for you to create better statistical models quickly. It has decent functional graphical capabilities, but it’s difficult to create complex graphical plots in SAS. R is known for In-memory analytics and is mainly used when the data analysis tasks require a standalone server. R is an excellent tool for exploring data. Currently, R has more than 5000 community contributed packages in CRAN. The wide range of packages and modules available for statistics and data analysis makes it the most popular and powerful language in data science. Statistical models can be written in a few lines of code. You can draw complicated graphs beautifully in R using packages like Ggplot2, lattice, rCharts, etc. Python libraries like Pandas, Numpy, Scipy and Scikit-learn makes it the second most popular programming language in data science after R. You can also create beautiful charts and graphs using libraries like Matlplotlib and Seaborn. Python is actively used by the machine learning community to scrap and analyze unstructured data from the web. I Python notebook – a web-based interactive environment – makes it easier to share your code with anther. Community Support SAS has an active online community moderated by community managers. These communities have evolved from peer to peer forums to become publishing platforms for essential content. You can ask queries related to SAS, and the community will answer them. The official blog of SAS is also an essential resource to refer to when you need help with a particular problem. R has 125 active user groups worldwide, and the number of user group meetings has increased by a significant amount in the last year. Python has 1,657 user groups, its communities strictly focused on data is much less when compared to R. R and Python have huge online community support from Stackover flow, mailing lists, user-contributed code and documentation. SAS doesn’t have an active open source community at all. Job Scenario SAS has more than 80,000 customers around the globe, and most of them are corporates with huge budgets. Analysts in these organizations use SAS to quickly and efficiently execute a wide range of statistical models on data sets. That is why the tile “analyst” is often mentioned in SAS job descriptions. On the other hand, R and Python are used by startups and technology companies. R is more inclined towards tasks related to statistics and data analysis because of which R related jobs have mentions like “ Data miner”, “ Statistician” , “ Data analytics manager”, etc.
Learn R programming from Edvancer.Meanwhile, given the boom in big data — projected by Ovum to grow 50 percent by 2019 on an already large base — you can expect increasing numbers of business analysts and other nonprogrammers to arm themselves with the R language as well. Whereas, Python is used by programmers that want to delve into data analysis or apply statistical techniques, and by developers that turn to data science. Python related jobs have mentions like “Machine learning engineer”, “ Data engineer”, “ Big data architect”, etc. Conclusion If your goal is to become a business analytics professional and you are planning to join a startup, then you should learn R first. On the other hand, if you want to join a bank or pharma company you should start with SAS and then learn R once you are comfortable with SAS. If you are looking to become a big data professional, then you need to learn either R or Python. This depends on your background as well. If you come from a statistics/ mathematics background then you should learn R; If you have a programming background, then you should learn Python. That ought to clear it up!
