slope-ratio assay for calculating relative potencyHi,
I am trying to analyze the relative potency of different samples. Parallelism test doesn't work this set of data. I was suggested to use slope ratio assay. Can anyone guide me how to do that? The figure is attached below.
Thanks,
HY

AnalyticsRe: slope-ratio assay for calculating relative potencyCan you fit a linear model and test parallelism?
Maybe try a log10 transform of time, and then fit a 3p model for testing parallelism?
