1261. A Method to Test the Adequacy of a Model to Observations
... It is well known that the Least Squares method returns the values of the parameters regardless the correspondence of the model to observations. ... The proposed method based on the orthogonal representation of the equations of a model is free of this fault since it tests the consistency of the model and data. This method have been used to find out the compatibility of the standard kinematical model with the proper motions of stars in the Hipparcos catalogue. ... What is beyond the accepted model? ...
