Advice to PhD Applicants

 To all students intending to do  PhD studies at the University of Venda under my supervision. 

 Please make sure you satisfy all the criteria below: 

  1.  You must have completed a masters’ degree in statistics, applied statistics, mathematical statistics, or data science. Must have published (or accepted for publication) at least one article in an accredited journal. 

  2. You should have obtained the equivalent of at least an upper second-class honours in statistics and merit (at least 70% at masters level). 

  3.  Sound knowledge of multivariate calculus, optimisation and matrix algebra. 

  4. You should be capable of programming with,  R  and/or Python.

  5. It is essential that you are familiar with reproducible research practices. 

  6. I work on probabilistic forecasting, time series, computational statistics, exploratory data analysis with applications in energy (load and renewable (solar and wind) ) and environmental systems.  If you have the background described above, then send me an email at caston.sigauke@univen.ac.za  including your CV, a transcript of your results and a concept note not exceeding 5 pages.
