<p>Next, we estimate both the reproduction success in the absence of neighbors (lambda) and the competition matrix (alpha). This is done by fitting a model that mathematically relates the reproductive success to the number of neighbors observed. In this first example, we fit the selected species with a Ricker model (‘RK’ model family, see vignette 4) and fairly standard initial valu
