Clopper-Pearson interval
What it means
The way to calculate the 95% interval of a frequency (for example, how often an opponent shoves or bluffs) from what you have seen. The lower bound is the lowest frequency at which seeing at least that result has a 2.5% probability; the upper bound, the highest at which seeing at most that result has a 2.5% probability.
Example
An opponent shoved 9 times out of 12 (75%): the 95% Clopper-Pearson interval runs from 42.8% to 94.5%. If your play's cut-off falls inside it, the sample doesn't decide yet.
