Abstract
Method of evaluating precision of output data using error propagation includes performing numerical differentiation using input data in data processing, and thereby obtaining a Jacobian matrix J of the data processing; estimating variance-covariance of errors of the input data, and thereby obtaining an error matrix D of the input data; and calculating an error matrix from the Jacobian matrix J and the error matrix D of the input data, the error matrix R representing variance-covariance of errors of output data.
