This function fits the Logistic Curve in population Data by Rhodes Method along with estimates of the parameters and predicted value.
rhodes.curve(p)rhodes.curve(p)
p |
a numeric vector |
Suppose we have n observations from population size corresponding to n equivalent time points say, at t=0,1,...,n-1. Here we assume the Logistic law of population growth , p=L/(1+exp(r*(beta-t))).
r.hat , L.hat , beta.hat : the estimated values of the parameters r, L and beta.
predicted.values : the predicted values of p
