If you are wondering what it is and if it suits your career, you have landed on the right place. This article will act as a guide for you in understanding all the important information about the PhD in computational statistics in an easy and understandable language.
What do you understand by a PhD in computational statistics?
A PhD in computational statistics is the highest achievable degree an individual can earn in this field. PhD is a shortened term for the “Doctor of Philosophy”. It basically trains you to perform new research instead of just using the existing tools.
The following is the breakdown of the PhD in computational statistics into 2 major parts:
- Statistics: Statistics is referred to as the science behind collecting, analysing, and understanding data. It helps an individual identify patterns and make good guesses when there is not 100% certainty.
- Computational: Computational, however, means using computers to perform the heavy work. Some statistics are too big to be solved on a piece of paper with a pen. Whereas computers can operate on millions of calculations easily to find an answer.
When you put them together, you will find a field that creates new computer-based methods for learning from the data. A candidate in this field is most likely to invent a faster and better way to analyse huge data sets or measure the certainty and confidence of the acquired results.
What is the curriculum of the PhD in Computational Statistics?
The standard curriculum of this programme is pretty simple, with almost no complications. The initial 2 years are mostly classes. Later on, most of the time is invested in research. The following are the core subjects that you will be introduced to:
- Probability: Probability is a mathematical term for establishing the chances of a certain event happening. It stands as the base for almost everything else in the upcoming curriculum.
- Mathematical statistics: This part of the curriculum is concerned with understanding how statistical methods work and the challenges that might affect them.
- Statistical computing: In statistical computing, you are taught how to write code that can carry out statistical methods better and faster.
- Linear algebra and calculus: These 2 are the basic math tools that are behind most of the data methods. Some schools even make it a must-have requirement before beginning the sessions.
- Machine learning: Machine learning is a concept that tells you how to make a computer learn from the data fed to it.
- Bayesian methods: This term might sound complicated, but it is simply a method of updating your existing knowledge as the new data arrives.
However, there are many programmes that require you to take a few more courses in other subjects, such as biology, economics, or computer science.
What are major topics in computational statistics?
When you have completed the initial 1 or 2 years of the PhD in computational statistics and have reached the research stage, you will now be required to work on a narrow problem. The following are some of the common topics of the PhD in computational statistics:
- Monte Carlo methods: The Monte Carlo methods are simple ways used to solve difficult problems. For example, they can be used to estimate an accurate value that does not have an easy formula.
- Markov chain Monte Carlo (MCMC): MCMC is a pretty common way that is used to explore complicated Bayesian models.
- The bootstrap: The bootstrap method is responsible for resampling your data as many times as possible to see how much your answer could change.
- Optimisation: Searching for the best answer to your questions out of many options is known as optimisation. For example, the best setting for a model.
- High-dimensional data: There might be some data sets that have more than thousands of measurements of each person; these data sets require special tools to handle them.
What are basic steps to be followed in the programme?
The exact set of rules and regulations for the PhD in computational statistics differs with every school or university. However, all of them follow a standard path.
The following is the general path followed by almost every institution:
- 1st year (mostly classes): The 1st year of the PhD in computational statistics is mostly about studying theory, methods, and probability. This time period is basically about making your base.
- Qualifying exams: There are various schools that basically test you on the basis of the 1st-year material. If you pass, it means that you are ready for research.
- Look for an advisor: An advisor is a professor who is responsible for guiding your research. Various universities require you to start looking for and find one by the end of the 1st year or the second.
- Research proposal: In the research proposal, the individual is basically asked to explain their research topic and procedure to a group of professors. At some institutions, it is even known as a prospectus or comprehensive exam.
- Research and writing: This step is pretty simple and direct. In this stage, you are required to work on new ideas, draft papers, and share the results at various conferences.
- Dissertation and presentation: After the research part is done, the next and final stage is to draft your research findings and create a dissertation. It is a long paper that presents your complete research. While presenting your dissertation, you need to explain it to the panel of experts and seniors along with answering their questions.
What are the skills that you create in the PhD in computational statistics?
The following are the important skills that you learn while studying for a PhD in computational statistics:
- Strong coding skills in programming languages like R and Python, along with some C++.
- Clear thinking skills, along with critical understanding and confidence.
- Careful writing, as you will be required to share your ideas in a detailed way.
What are the eligibility requirements for applying for a PhD in computational statistics?
The exact set of eligibility rules might differ on the basis of each school or institution, but there is a standard criterion that is followed by almost every university.
The following is the standard eligibility criterion for applying for the PhD in computational statistics:
- A graduation degree (in statistics, maths, computer science, or a related field).
- Good marks in math-related courses (specifically linear algebra and calculus)
- Basic programming experience.
- Letters of recommendation from teachers or research mentors
- A personalised statement draft that would explain your reason for doing the research.
Some programmes even require your test scores, whereas many have eliminated that criterion. For the exact information, you must look at the institution's page itself. There are even some universities that do not ask for a master’s degree and accept you with a bachelor’s degree.
What are the jobs that you can get after the PhD in computational statistics?
A PhD in computational statistics is a degree that will make you accessible to both institutions and industries.
The following are the most common job profiles that you can consider after a PhD in computational statistics:
- University professor who would teach and even run their research group.
- Research scientist who will be required to work in a company or a lab around solving new data problems.
- Data scientist who will be responsible for creating models and studying data in order to help a business in deciding what to do next.
- A biostatistician who is required to study health data, usually for hospitals, drug companies, or public health groups.
- A government statistician who is responsible for working and collaborating with agencies that measure factors such as jobs, prices, and health.
- Finance and insurance expert who will be required to develop models that are used to calculate the risk or predict the results.
- Machine learning researcher who is asked to create and design new learning methods for computers.
Conclusion:
A PhD in computational statistics is about learning new ways of learning from data with strong maths and strong coding. It’s normally about five years, and a lot of the programmes are funded for students who study full-time. BLS predicts steady job growth in this field, and graduates can work as professors, researchers, data scientists, and more.
It is a slow, hard road, but it can be a rewarding one for people who love data, computers and big questions. Select your programme very carefully.
