This analysis can do any or all of these tree things:
•Handle zero concentrations differently. Zero concentrations are sometimes a problem because the logarithm of zero is not defined, so zero concentrations are lost in a log transform. With this analysis, you can specify that zero be substituted with a low value (say 109) before taking the logarithm.
•Change units, for example from molar to nanomolar. Simply tell Prism what constant to multiply or divide by.
•Transform to logarithms, often needed prior to fitting a curve.
