Patent ID: 7171343

Claim:
A computer program product for computing interval parameter bounds from fallible measurements, comprising instructions for: receiving a set of measurements z 1 , . . . , z n , wherein an observation model describes each z i as a function of a p-element vector parameter x=(x 1 , . . . , x p ), wherein receiving the set of measurements involves receiving values for a set of conditions c 1 , . . . , c n under which the corresponding observations z i made, wherein equations in the system of nonlinear equations account for the conditions c i , and are of the form z i −h(x|c i )=0 (i=1, . . . , n), and wherein each condition c 1 is not known precisely but is contained within an interval c I i ; storing the set of measurements z 1 , . . . , z n in a memory in a computer system; forming a system of nonlinear equations z i −h(x)=0 (i=1, . . . , n) based on the observation model; and solving the system of nonlinear equations to determine interval parameter bounds on x.
