Freelance IT engineer: SAS engineer Characteristics and work of programming languages, is it difficult to learn?

Freelance

The SAS language is software for analyzing statistical data, and it is a very niche field where there are few engineers. Perhaps because of that, the reality is that not many people know about it. So how difficult is the SAS language said to be difficult to learn? I will also explain how long it will take you to be able to program.

History of SAS

SAS is an abbreviation for Statistical Analysis System, and this system is statistical software developed by an American company called SAS Institute. Originally, this software was a fairly niche language used only at a research institution, and was used at North Carolina State University. By the 1970s, about 100 customers had gathered outside of the university, and when they realized there was demand in the commercial world, SAS began selling the software in earnest. In the 1990s, an education department was established within SAS, and we also introduced licenses for schools.

Against this background, SAS was originally used as analysis software, but it has become commercially available in various industries, so it can also be used for system development. Currently, it is used not only in the pharmaceutical industry, but also in the finance, insurance, communication, distribution, and Internet industries, and is used not only for data analysis but also for system development.

What are the characteristics of the SAS language?

The SAS language has the following characteristics: Unlike open source such as Java, it has different characteristics. Let’s check the following points when using it to learn knowledge and skills. There is a certification exam for the program, and some people obtain the qualification, so it is in high demand. Also, SAS does not often require machine learning in practical work.

Data processing

SAS is very fast at processing data. Specifically, data is aggregated, processed, formatted, extracted, converted, and converted into the format required for analysis and reporting. It has the advantage of being faster than other languages.

data analysis

SAS engineers may also be involved in model building and algorithm development for data analysis. SAS has a library specialized in statistical analysis methods and performs advanced analysis. This looks very difficult, but it can be achieved by executing a very simple procedure.

System development and operation

SAS engineers may be involved in system development and operation using the SAS system. SAS systems are often used by large companies such as financial institutions and insurance companies because they can process large amounts of data and perform advanced analysis. We also do customization and migration work.

reporting

A SAS engineer’s job includes reporting. Create an analysis report by summarizing the analysis results in graphs, charts, tables, etc. Analysis reports are very important information for companies to formulate management strategies and marketing strategies.

Difficulty level of SAS language Is it a difficult language?

I will specifically explain the difficulty level of the SAS language. You’ll see that it’s very easy to do below. We will introduce details at the code level, so if you are interested, let’s start learning. Business requires skills such as SQL, and it is necessary to understand and master databases. It has been used in some AI, web, and projects. Let’s start by learning the general data and proc steps.

very simple

A feature of SAS is that it is very easy to write processes. If you only remember the Data step and Proc, you can do most of the processing. It is written in a concise manner, making it very beginner-friendly. As your skills improve, try adding multiple sentences and making them move. It’s basic so try to do both. You can acquire specialized skills, increase your value, and potentially advance your career.

Data test;

set sample;

a = 1;

run;

Proc sort data = test1 out = test2;

by subject;

run;

Statistical testing made easy

A feature of SAS is that it is very easy to write processes. If you only remember the Data step and Proc, you can do most of the processing. It is written in a concise manner, making it very beginner-friendly. As your skills improve, try adding multiple sentences and making them move. It’s basic so try to do both. You can acquire specialized skills, increase your value, and potentially advance your career. Let’s try R language etc.

Proc freq data = test;

  tables A*B / chisq;

output out = out1 chisq;

run;

scripting language

When people with experience in other languages come into contact with SAS, what they say is that it is very similar to scripting. SAS is not solid. There are only character and numeric types. So it’s easy. SAS is very similar to PHP, so people who have used PHP will find it very familiar. In addition, it is easy for people with experience in other languages such as c++, cobol, html, go, and VBA to be familiar with it, so they can respond efficiently.

graphing

SAS products have a feature called SAS Graphs. Graphs using datasets may seem very difficult, but you need to play around with the settings for those graphs, but if you just draw them, you can easily achieve them as shown below. Nowadays, it is of course sometimes used in different fields such as marketing.

Proc sgplot data = sample;

vbar age;

run;

Time required to learn SAS

It doesn’t take long to learn SAS. But it will depend on the case. Recently, there are cases where people with experience in other languages are starting the course. If you keep the basics down, you will be able to find a job easily. There aren’t that many types to memorize, so please look forward to it.

programming inexperienced

If you have no programming experience, it is better to estimate about a year before learning. What is programming in the first place? must start from And I think it’s a little long because you need to know how to actually move your hand and how it moves.

programming experience

If you have programming experience, you will probably be able to do basic operations in 3 to 6 months. I think you will be able to produce city frequency tabulations, summary statistics, and even statistical tests, so you don’t have to think so hard. In SAS, there are actually engineers who have taken freelance work even if they have no experience in three to six months.
