DEscription of the factors in sensitivity analysis methods

<div class="content wysiwyg-content">
I am in the process of entering Dixon and Mood's Up-and-Down Method into an Excel Spreadsheet for performing sensitivity analysis. &nbsp;I'm not finding a table value for the G factor that is multiplied by the population standard deviation and divided by the square root of N to arrive at the standard error of the estimate on page 115 of the article. <br />
<br />
The handwritten document I'm working off of multiplies the standard error of the mean by a factor called C and this result is subtracted by the W50 test result, M, to obtain the lower 95%- confidence level mass of material. &nbsp; It looks like a z-score but the z-value of 1.8333 corresponds with 96%, not 95?<br />
<br />
Making a long story short, I am looking for the table values or calcualtions for G and C.<br />
<br />
Thank you.

Up-and-Down Method Factors

The Math / Science topic primarily includes discussions of mathematics, physics, statistics and economic analysis, but also biology, chemistry and other sciences.
