Thanks! I mostly used OBS, which is an open source tool for recording and streaming. I found it quite intuitive (with some tutorials), and as someone without any editing experience was able to set up a good simple system for switching and layering windows. (Though to be honest, this was amid early pandemic despair over how to manage online teaching, so I probably did spend quite some time on it). For the weather-person effect of talking in front of a screen, I bought a pull-up greenscreen, though since then I think automatic background filtering has come a long way, so a greenscreen might no longer be needed. I also used Kdenlive for editing. In my case I only used this for cutting and pasting pieces of recordings, which didn't really take long to figure out, but I think that tool also supports more advanced editing.
I dont't think those are in Piketty's data, no. The Japan in Europe thing is off course incorrect, but was just to get a simple comparison between 2 groups (for the ttest). In the tutorial we note this, but here I forgot to mention it. In any case, please do not view this video for the analysis, its purely about how to perform some basic tests in R
The link you provided did not work for me so I searched for the Picketty data instead and found a site called the World Inequity Database that contains a large dataset. Is that what you got your data from?
