WebMay 6, 2024 · You could, for example, weight each count by dividing it by the square of the distance it occurs at. However, you were indeed talking about probability of counts occuring in circular rings around an origin, I would expect to see a number of distances that were nearly the same.

WebDec 29, 2015 · Circular Error Probable (CEP) The Circular Error Probable CEP (p) for p \in [0,1) is the estimated radius of the smallest circle that is expected to cover proportion p of the shot group. Some authors restrict the name "CEP" to the case of p = 0.5, and refer to, e.g., R95 for p = 0.95. We make no such distinction here.
