All those “accessibility encounters” of mine left me with a pile of unstructured notes and advice to my self to which I often refer. Well, I decided to blog about parts of it in case anyone else finds it useful. http://www.ikosmidis.com/post/blog-workflows/ Tue, 18 Jun 2019 00:00:00 +0000 http://www.ikosmidis.com/post/blog-workflows/ In early 2019, I was invited to give a talk at the Young Researcher’s Meetings of the Department of Statistics at University of Warwick (the place I work). The Young Researchers’ meeting is a weekly seminar for postgraduate students and postdocs to discuss research and exchange ideas. My immediate thought was to talk about one of my current and exciting research projects. Of course, I know from experience that the talks I have given on research projects I am excited about are not necessarily equally exciting for the audience. http://www.ikosmidis.com/post/blog-bartlett/ Sun, 09 Sep 2018 00:00:00 +0000 http://www.ikosmidis.com/post/blog-bartlett/ It is one of those times that I am really excited and somewhat obsessed with the current research project I am working on. It is an old idea that after many years going around my head, it seems to be coming close to fruition. This is not the reason I am writing though. Part of that research project involves heavy usage of the Bartlett relations (or Bartlett identities). The Bartlett relations (see Bartlett 1953, sec. http://www.ikosmidis.com/post/blog-logo/ Sat, 03 Mar 2018 00:00:00 +0000 http://www.ikosmidis.com/post/blog-logo/ My logo in GitHub (see here) is the contours of the density function of a mixture of bivariate normal distributions (see Figure 1). The idea came to me when I was working on the paper Kosmidis I and Karlis D (2016). Model-based clustering using copulas with applications. Statistics and Computing, 26, 1079–1099 DOI ArXiV In that paper, amongst several other things, we introduce the use of rotations of the components of mixtures of copulas to define extremely flexible mixture models.
