PGDAST is concerned with applied statistics. As a result, it requires fewer proofs. There are more theorems, formulas, and methods to employ. While a Masters's program contains numerous proofs as well as an applied component. However, PGDAST will undoubtedly improve your statistical knowledge. Furthermore, statistics have numerous applications in computer science and big data/data research. As a result, it will undoubtedly improve your career prospects. This is especially true given the scarcity of computer engineers who are also statisticians. And statisticians are in high demand in information technology firms. So you have an advantage over others.

It does not entitle you to study higher mathematics or statistics at any Indian university or IIT. Because PGDAST is only a one-year program, as opposed to MSC, which is a two-year program. PGDAST can also be completed by graduates from any discipline. While a Master's in Statistics requires a minimum three-year Bsc degree in Math/statistics. The PGDAST program is a diploma program.

You should go for it if you want to learn statistics. It will undoubtedly be a rewarding experience. One year of effort is not excessive. You must be consistent. To be eligible to sit for term-end exams, you must complete assignments. Even if you do not consider the benefits of computer science, it will almost certainly foster a new way of thinking.
