The results showed that the proposed exponential ratio estimator was more efficient compared to the usual sample variance estimator and the proposed ratio type variance estimators in adaptive cluster sampling, assuming given conditions.
The most common way of adaptation is the adaptation to the variance of the signal in which the frame sample variance calculated and one from a set of quantizers is selected.
As in other robust procedure, the fixed sample variance of the estimator cannot be expressed in closed form.
This shows sample consistency for white light interferometry and a low sample variance or a high repeatability with white light interferometry between the three measurements at each point across the film.
