need help: regression models
hello,
I am working with some data which i would like to find the best fit model for them.
First, this data are in a matrix. Each of the columns are treatments and the raws are repetions for the each tratment.

Therefore, i need to find the best exponential model for this data, and i would like draw this tend...
