Abstract
Methods and systems to correct low-resolution measurements corresponding to unobservable high-resolution measurements by introducing variation in the plurality of low-resolution measurements to obtain perturbed values for the low-resolution measurements. The perturbed values have a higher resolution than another resolution of the low-resolution measurements. A distribution test is performed on the perturbed values.

A method comprising:
- measuring, by a low-resolution measurement device including at least one sensor, a plurality of low-resolution measurements, the plurality of low-resolution measurements being quantitative measurements that are rounded versions of a corresponding plurality of unobservable high-resolution measurements and therefore having a lower resolution than the resolution of the corresponding plurality of unobservable high-resolution measurements;
- introducing variation to the plurality of low-resolution measurements by iteratively computing, until a termination criteria is met, corresponding perturbed measurements for the low-resolution measurements, said corresponding perturbed measurements having a higher resolution than another resolution of the low-resolution measurements, a first final set of corresponding perturbed measurements being obtained after the termination criteria is met;
- performing the introducing a predefined number of times to obtain other final sets of corresponding perturbed measurements;
- identifying the final set of corresponding perturbed measurements having a median shape parameter;
- running, a distribution test for a Weibull distribution on the identified final set of corresponding perturbed measurements.
