As an honours year (Australia) student I am doing a methodological statistics research topic relating to multivariate time series under structural breaks.…

Hi! We are doing a research paper for a veterinary med subject where we will test an effect of a certain GAG on a chicken embryo. Question is, what would be the best sample size to use? I can only think of using G Power, but from there how do I do it?…

Around June to August 2027 I will be graduating with a PhD in Statistics from one of the top 10 programs in the USA. For quite a few years I was convinced I wanted to pursue a career in academia.…

Hi everyone, I'm in my last semester of a Master's program in Applied Mathematics (with coursework in statistics and numerical analysis), and I'm currently applying to Statistics PhD programs.…
