I have 9 data sets from an enzyme inhibition experiment. In a Simbiology model I can estimate a global rate constant ki using the individual fit task, NLINFIT with pooled data. I now want to repeat the global ki estimate but allow another parameter (the substrate concentration, S) to be fitted locally to each data set i.e. to vary or optimize for each curve. Is this possible in Simbiology? thanks, Lambro.
