    Snippet: We estimate the best-fit model solution to the reported data using nonlinear least squares fitting. This process yields the set of model parameters Q that minimizes the sum of squared errors between the model f ðt; QÞ and the data y t ; where Q GLM ¼ (r, p, K), Q Rich ¼ (r, a, K), and Q Sub ¼ (r, p, K 0 , q, C thr ) correspond to the estimated parameter sets for the GLM, the Richards model, and the sub-epidemic model, respectively; parameter.....

Thus, the best-fit solution f ðt; b QÞ is defined by the parameter set b Q ¼ arg min P n t¼1 ðf ðt; QÞ À y t Þ 2 . We fix the initial condition to the first data point.
