Prior Art details previous work on the problem of estimating shooting statistics.

CEP literature focuses on the broader body of work related to characterizing Circular Error Probable, which is applicable not only to ballistics but also to fields like navigation and signal processing.

Following is a complete list of References and Prior Art:

Important Note on Siddiqui: Siddiqui parameterizes the Rayleigh distribution with \(\frac{\sigma}{\sqrt{2}}\). Therefore, should you endeavor to relate Siddiqui's work to that referenced here and in more modern usage, remember that \(\sigma_{modern} = \sqrt{2} \sigma_{Siddiqui}\).
