Inaccurate observations are described as casual observations, therefore, most often detail and information is lost. This error occurs frequently. Eye witness testimony error is one example that comes to mind. Since daily observations are casual and semiconscious I wonder how many times their have been errors in eye witness testimony? An error may be defined as the difference between the measured value and the actual value. For example, if the two operators use the same device or instrument for finding the errors in measurement, it is not necessary that they may get similar results. There may be a difference between both measurements.

2013-11-08 · The four major objectives of the study were: 1) estimating and examining variation in the magnitude of observation and process error; 2) quantifying the contributions of ecological and Failure to obtain data from parts of the survey population which results from two sources: noncoverage and nonresponse. The optimal analysis state, xa, is given by the solution to the cost function J(x) = 1 2 (x−xb)TB−1(x−x b)+ 1 2 (y −Hx)TR−1(y −Hx), which penalises distance from the background state xb and the observations y. Now, suppose that it is known that the observation may be in error, but there is no knowledge of the mechanism by which these errors occur. For a given forecast, let o e denote the error‐prone observation and let q = Pr(o e = 1).
