Pick a point uniformly at random in a square and connect it to the bottom-left corner of the square.

An -sided fair die is rolled repeatedly.

I recently learned from Allen Downey’s blog that Our World in Data is providing API access to their data.

The fused lasso, introduced in Tibshirani et al. (2005) (Reference 1), is an extension of the lasso.

Set-up Assume that we have p-values .
