Closed Form Equation for Spherical Error Probable (SEP)
(OP)
Hi.
Does anyone know of a closed-form equation for the Spherical Error Probable (SEP) 95% or 99%?
Thanks,
Tina

RE: Closed Form Equation for Spherical Error Probable (SEP)
Even assuming a Gaussian distribution, the "closed form equation" will require a numerical integration (or solution of a numerical series).
If you haven't guessed by now, your "closed form equation" seems nonsensical in real world conditions, with real world devices. You will need to define an algorithm, and probably conduct a series of worst-case estimates, then an exhaustive Monte Carlo simulation, and finally a test series to verify the estimates from the Monte Carlo models.

In any case, the application is not important here.
And yes, this is Gaussian distributed.
There is a closed form equation for the SEP 50% probable. I just need it for 95% and/or 99%.
Thanks again.

RE: Closed Form Equation for Spherical Error Probable (SEP)
I am not sure if there is a reasonable (accurate enough) approximation, the ones I have seen have not been. I figured I'd try this forum and see.
