1. Dear Professor Pommerening,

   I trust this email finds you well. I am Jerry a master student with Kyushu University, Japan. I am trying to use the Gompertz function to estimate CAI and MAI with my data. I have been able to estimate the CAI but challenged with the MAI.
   Principle: I used the first derivative to estimate the CAI. With the MAI, I divide the function by t, equating it to the first derivative (CAI), {implying tbexp(a-bt)=1}
   Gompertz Function: y=Aexp(-exp(a-bt))
   From the first derivative, CAI (t1) =a/b
   I get MAI value less than t1 always.
   Am I doing something wrong?

   1. For MAI you just need to fit the growth function and divide any of the values of the growth function by t.
