  Body: You can use quantile regression tricks to make predictions about quantiles. 
  
  But what if, at prediction time, you'd like to predict `P(y >= value)`? 
  
  To answer that question you'd need more than just a quantile you'd need some distribution prediction instead. 
  
  So maybe there's an opportunity for a component here.
