Dear Justin:

I really appreciate your response and help!

I am confusing about the result by using this method. I found in B. Hess's paper (Appendix, JCP, 116, 2002) that " this gives a standard error estimate for 1/eta of 29.5. "; and the error he gives for that eta is 0.006. I thought the error should be calculated as 1/29.5=0.034. Thank you again for your help!


The relationship is not a simple inversion as you've shown it. That is, (standard error of 1/eta) != 1/(standard error of eta). The standard error calculation depends on a number of factors, hence all the math in the Appendix :) An example is given in Fig. 8 of that paper.
