I seek help with nonlinear regression for my data. I've run intro trouble fitting a model to my data as follows:
rate_parameter stable_population 75 1996.1277 100 1623.2979 125 1362.3475 150 1164.6738 175 1014.8227 200 892.0851 225 794.1844 250 710.1489 275 639.6738 300 578.0496 325 525.4965 350 479.4752 375 440.3050 400 402.4397 The "rate_parameter" here will be my independent variable which affects the "stable_population" quantity in an agent-based simulation. I can see that the plot of this data seems to fit an exponential decay. I would greatly appreciate if someone could help me out with this task. I've found the following info on this page helpful: https://stat.ethz.ch/pipermail/r-help/2001-December/017330.html yet, still unable to grasp what I need to do.
