Using the same language as SAS, Stata is easier to learn and is designed to be an economical solution for a variety of statistical analysis problems. While Stata is a good choice for basic data analysis, it is less useful for complex information technology problems such as data management, file structures, and networking.
SAS on the other hand is an extremely powerful programming language that provides a wealth of capabilities. Even though SAS comes with pre-defined data types, Stata can open the door to custom-built data types and provide a solid foundation for creating accurate and error-free data sets.
Although the two languages provide a similar number of features, they do differ in their uses and complexity of their implementations. Stata is very different from SAS in its extensive built-in feature set and the way it is run.
Both SAS and Stata provide dynamic memory allocation, the ability to run asynchronously, and the ability to use functions for linear and nonlinear regression. However, Stata has a richer feature set that includes a full range of mathematical operations including basic mathematics functions, functions for integration, data conversion, functions for matrix multiplication, and functions for root finding. SAS does not have a full range of mathematical functions.
The usage of Stata is still relatively limited compared to its competitors. Using only functional programming is a major weakness of Stata. As a result, Stata’s performance compared to SAS is not always as good as it could be.
Another major difference between Stata and SAS is the use of GUIprogramming environments. Although Stata can be used in a variety of environments, such as graphical user interfaces, it can also be used as a command line interface.
Stata also has a number of historical reasons for offering greater functionality than SAS. Although the former is equipped with state-of-the-art systems for automatic and semi-automatic data cleansing, SAS only offers automated data cleaning and batch data maintenance.
This difference is caused by the fact that Stata is more versatile than SAS and it is designed to be easier to use for beginners. Despite its greater functionality, Stata does not provide as much customization as SAS does.
One major advantage of using Stata over SAS is that it supports very basic mathematical operations such as linear equations, trigonometry, and geometric figures. It can also handle more complex calculations such as partial sums, limits, and line graphs.
The Stata interface can be edited or modified, while the SAS interface cannot be edited. This is a major weakness in the Stata interface because it can negatively affect the accuracy of the computation and when this happens, it is necessary to repeat the operation.
Statistics and analytic applications require the use of both systems for smooth, accurate results. For most data analysis, it is better to use Stata and this will be reflected in your final statistics.
