Adjustment and data analysis
Abstract
The determination of the final values for the gravimetry data base (DSGN76) requires adjustment and data analysis including the reduction of groups of parameters from the normal equations, variants for adjusting a free network, supplementary restrictions, and iterative variance estimation. The final set of parameters and the forming of weight groups is decided on the basis of numerical results for parameters and residues. Thus data analysis becomes an integral constituent of model development.
