CEP allows the nation’s highest poverty schools and districts to serve breakfast and lunch at no cost to all enrolled students without collecting household applications.
The Community Eligibility Provision (CEP) is a non-pricing meal service option for schools and school districts in low-income areas. What does comparing missiles CEP stand for? For the 1-D case, for example, measuring the length of a line between two points, the accuracy is expressed by the so-called root mean square (rms). The term accuracy is used to express the degree of closeness of a measurement, or the obtained solution, to the true value. These terms are Standard Deviation and Variance, Root Mean Square (RMS), Mean Square Error and Standard Error. A common source of confusion occurs when failing to distinguish clearly between the standard deviation of the population (), the standard deviation of the sample (), the standard deviation of the mean itself (¯, which is the standard error), and the estimator of the standard deviation of the mean ( ¯, which is the most often calculated. The aim of this paper is to clarify some confusing nomenclature of some statistical terms frequently used in the surveying literature.
Thus, 2drms is a very confusing abbreviation: It is a two-dimensional measure, but the “2d” usually stands for twice distance. Misconception Number 2 - 2drms means “two-dimensional rms.”In fact, 2drms usually stands for “twice distance rms,” in which the “distance” is measured in a 2-D space, the horizontal plane. So a receiver with 1 meter CEP accuracy will be within one meter of the true measurement 50% of the time.
What is CEP value?Ĭircular Error Probability or CEP is defined as the radius of a circle centered on the true value that contains 50% of the actual GPS measurements. In the military science of ballistics, circular error probable (CEP) (also circular error probability or circle of equal probability) is a measure of a weapon system’s precision. So the CEP for 50% would be the distance within which half the points would lie closer to a specific location. The CEP is determined by the number of points within a certain distance of a specific location as a percentage of the total number of points.
