Logistic 3P parameters calculation
I´m currently working on a prediction model using Logistic 3P fit with JMP. I´m obtaining very good curves using the calculated fit model. The model is the following:y= c/{1+exp[a*(x-b)]}Where a is the growth factor, b is the inflexion point and c is the asymptoteMy specific doubt is the following, How can I obtain a, b and c?I need to justify my model with my data. Looking in my script, it only s...
