Prism presents the formula (which is in the Prism equation library as

Thanks so much! It works great.
I had thought the way to do it relied on combining the data sets, but I
couldn't figure out how to alter the formula to work
I'm attempting to insert variables as expressions into labels for my plots,
but I'm running into the issue that characters in my labels aren't allowed
in expressions, notably '[' and ']'. An input string of [^3H]5-CT needs to
be displayed as [3H]5-CT with the 3 as superscript. But brackets aren't
I'm working with 3 different data sets and applying this non-linear

Previously, all of the regressions were calculated in Prism, but I'd like to
