docs are out of date it seems! I'll have to update. Do you want a smooth graph over a step graph?

Can percentiles also be scaled to be between 0 and 1? Ex: does it make sense to say percentile(array, 0.5) (the median)?

comment Python Astronomy Censored Data in Lifelines
Well ok actually you can use lifelines, but it's a hack on the definition of correlation. There is a measure called the concordance index which is used to measure survival prediction. Instead of comparing values, it compares ranks: if x_i < x_j in one dataset, is y_i < y_j in the other dataset? It deals gracefully with right-censored data as well. It's a value between 0 and 1 (1 being perfect, 0.5 is random, 0 is opposite); if you normalize the concordance index to be between -1 and 1, you get a sorta correlation (but please don't call it that). Here's a script to do it in lifelines:
