* We can define the cdf for X<=x_observed
* Set p such that the observed result is a median for the CDF

Comment: setting p so that the observed result is a median is not the same as a max entropy approach? CDF and entropy of different sets of states are different tings? I added a script to calc max entropy for coins and then stars. I haven't yet confirmed not equivalent to taking CDF approach but I don't think CDF factors in the concavity needed to land on the max entropy solution.

* And relate all this to the binomial problem solved in Nassim's blog

### Application Notes
* This is mainly useful in the small sample space, where you have a handful of reviews (with less you can't do much, with more than 30 or so the binomial starts to converge to it's true generating distribution (law of large numbers))
