See also the package vignettes and the cranly GitHub page for more details. Take a look at my Software page for the cranly directives network for my R packages and for how to make your own! 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.
