See the CEP literature overview for **references and the shotGroups package** for a free open source implementation: The general correlated normal estimator (DiDonato & Jarnagin, 1961a; Evans, 1985) is based on L. (1992). "A feasible Bayesian estimator of quantiles for projectile accuracy from non-iid data." Journal of the American Statistical Association, vol. 87 (419), pp. 676–681. One missile misses with 0.944 probability, the chance of having this event occur ten times in a row is: p(all miss) = 0.94410 = 0.562 Thus the chance of at least It generalizes to three-dimensional data and can accommodate systematic accuracy bias, but it is limited to the 50% CEP. http://trinitylabsupply.com/circular-error/circular-error-probable-formula.html

The MSE will be the sum of the variance of the range error plus the variance of the azimuth error plus the covariance of the range error with the azimuth error

Precision-guided munitions generally have more "close misses" and so are not normally distributed. C. The Ignani (2010) estimate is based on a polynomial approximation for the 50%, 90%, 95%, and 99% quantiles of the Hoyt distribution.

Circular Error Probable Gps The smaller it is, the better the accuracy of the missile.

CEP is not a good measure of accuracy when this distribution behavior is not met. Spherical Error Probable Lieber and Daryl G. R. The tables were later cast into an algebraic form that is essentially the Rayleigh estimator with a weighted average of the variances of the de-correlated data to estimate the true standard

In three dimensions (spherical error probable, SEP), the radial error follows a Maxwell-Boltzmann distribution. http://www.alternatewars.com/BBOW/ABC_Weapons/Nuke_Exchange_Calcs.htm What is the SSPS? 0.5 (250/1000)^2 = 0.957603 or 95% Calculating the Lethal Radius of a Warhead versus a Target for a Groundburst LR = 2.62 * Y(1/3) / H(1/3) Where: Circular Error Probable Excel Fill in your details below or click an icon to log in: Email (Address never made public) Name Website You are commenting using your WordPress.com account.

To incorporate accuracy into the CEP concept in these conditions, CEP can be defined as the square root of the mean square error (MSE). his comment is here It is defined as the radius of a circle, centered on the mean, whose boundary is expected to include the landing points of 50% of the rounds.[2][3] That is, if a The RAND-tables have also been fitted with a regression model to accommodate systematic accuracy bias in the 50% quantile (Pesapane & Irvine, 1977). Ehrlich, Robert (1985). Circular Error Excel

The Rice distribution reduces to the Rayleigh distribution if the mean coincides with the POA. A 90 % chance at a hit means that the chance of all missiles missing is 10 %. and Bickert, B. (2012).

Annapolis, MD: Naval Institute Press. 2drms See the literature overview for more comparison studies. The Grubbs-Liu estimate was not proposed by Grubbs but can be constructed following the same principle as his original estimators.

E. (1964). The Valstar estimate (Puhek, 1992) for the 50% quantile of the Hoyt distribution differs from the RAND-estimate only for highly elliptical distributions. Other old, and less relevant approximations to the 50% quantile of the Hoyt distribution include Bell (1973), Nicholson (1974) and Siouris (1993). Cep Complex Event Processing Inventing Accuracy: A Historical Sociology of Nuclear Missile Guidance.

It assumes an uncorrelated bivariate normal process with equal variances and zero mean. In the literature this is referred to as systematic accuracy bias. If you know the exact coordinates of the location where the data was collected, select the "Known Coordinate" option and enter in the coordinates. navigate here p.342. ^ a b Frank van Diggelen, "GNSS Accuracy – Lies, Damn Lies and Statistics", GPS World, Vol 18 No. 1, January 2007.
