I am trying to fit my data with a built fitting function (y= R0-exp(-(ks*t)^kl))
When I fit sample 1 data using the equation above the model cannot fit the data (Fit Status code -207 Fit did not converge – reason unknown).
However, when I fit the sample 1 data using the same equation after successfully fitting sample 2 data using the recalculated mode :Auto, the fitting succeeded.
Please what can be the possible reason for this outcome.
Why sample 1 data can only fit after replacing the data of sample 2 previously fitted using recalculated mode auto?.
Sincerely.
You should have provided a reasonable initialization of parameters for sample 1.
Show your both samples and parameter initializing code.
