    Can you fix the boss's mistake if you're only given the sorted data? ie is regression even possible if we only see uncoupled Xs and Ys? This nice paper says yes (!), if the regression fn is non-decreasing (but it's hard & error decreases slowly with n) https://arxiv.org/abs/1806.10648 https://twitter.com/andrewheiss/status/1093667046808682497 …

        Quote from Degroot and Goel 1980 cited in that paper (https://projecteuclid.org/euclid.aos/1176344952 …): [Estimation in this setting is] "like a dog's walking on his hinder legs. It is not done well; but you are surprised to find it done at all."pic.twitter.com/apE3JX4nmd

        Until proven otherwise, I will assume that this is requires evil magic, or that this was written by a really skilled troll.

        I love it when you can do things that are seemingly magic in statistics.
