The authors (Meredith Reba, Femke Reitsma & Karen Seto) write: How were cities distributed globally in the past? How many people lived in these cities?

ropenaq, a breath of fresh air/R

A plot against the CatterPlots complot

In these terrible times, we R people have more important subjects to debate/care about than ggplot2 vs. base R graphics (isn’t even worth discussing anyway, ggplot2 is clearly the best alternative). Or so I thought until I saw CatterPlots trending on...

I have an educational background in economics, so I have spent a good deal of time studying and using linear modeling in it’s various forms. However, I have spent little time with the various classification techniques. Gaussian mixture modeling has...
