This paper examines and refutes a conjecture, to the effect that the solution set for a general (real) static errors-in-variables problem is a union of convex polytopes. The conjecture is disproved, through det
The usual assumption in the classical errors-in-variables problem of independent measurement errors cannot necessarily be maintained when the data are time series; errors may be strongly serially correlated, possibly containing seasonal effects and trends. When it is possible to identify frequency bands...

It has long been known that the Errors-In-Variables (EIV) Model is a special case of the nonlinear Gauss–Helmert Model (GHM) and can, therefore, be adjusted by standard least-squares techniques in iteratively linearized GH-Models, which is the approach by Helmert (Adjustment Computations Base...
When using shared variables in LabVIEW I have observed multiple errors and warnings: What can I do to fix these errors and warnings?Solution LabVIEW shared variables are classified into two types: Single-process shared variables: these are similar to LabVIEW global variables and generally do not...
The problem formulation with additive error on both the input and the output, however, is more symmetric then the classical Kalman filter one and allows interpretation in terms of misfit and latent variables.关键词: Kalman filters continuous time systems linear systems state-space methods Kalman ...
The name "%.*s" is not permitted in this context. Valid expressions are constants, constant expressions, and (in some contexts) variables. Column names are not permitted. 129 15 No Fillfactor %d is not a valid percentage; fillfactor must be between 1 and 100. 130 16 No Cannot perform an...
As we saw earlier, errors can be stored in variables. Errors can also be included in data structures, such as tables. This is an important so that an error on any one record can't invalidate the entire table.For example, consider this data table control in Power Apps:...
