Nonlinear modelling and parallelism graphs not displaying
Hello! I am trying to graph a few sets of data to test parallelism against each other using the the nonlinear modeling. However, when I enter the data and fit my curves, it won't display anything in the graphs themselves. It will show the individual points for each set but won't show the overlapping graphs. I'm sure I can use the predicative formula generated from the fit to create the graph in gr...
