What is the Gaussian copula and how to use it to derive the joint probability of the default of two assets? This is an interesting question, but I would like

I have a Gaussian distribution like this in 2d. You know its variance is 1 but don't know its mean. I randomly pick a point (x₁,x₂) according to this

@dabacon but also @nick_c_rubin thanks for engaging, I am enjoying the tweeting over multiple drinks. One argument you cite is the mitigation of systematic errors and using this method as

Good to see this analysis, but misleading headline. 24 states have *point estimates* over 1, but uncertainty in estimates is large. Let's consider null hypothesis that Rt=0.95 everywhere. Then would

So a lot of you are sharing the projections from IHME (https://covid19.healthdata.org/united-states-of-america). I want to draw your attention to a very optimistic assumption in their modeling.1/ Let's look at this
