文摘
- •
We proved improper data processing and experimental design can cause large disparity in parameter estimate.
- •
We found the estimate of pre-exponential factor C is subject to prohibitively large error (>10%).
- •
We suggested minimizing the uncertainty of k estimate to gain more accurate overall estimate on other parameters.
- •
We proposed a practical OED-based sequential procedure able to reduce uncertainty in parameter estimate by half.
