The four models considered for estimating the mode of growth of the cancer cells based on data from monoculture spheroids seeded at a low density of 10,000 cells.

Growth model	Equation	Parameters
Exponential	$\frac{\text{dN}}{\text{dt}}=\text{rN}$	r is the instantaneous per capita growth rate N is population size K is the carrying capacity
Logistic	$\frac{\mathit{dN}}{\mathit{dt}}=rN\left(1-\frac{N}{K}\right)$
Gompertz	$\frac{\mathit{dN}}{\mathit{dt}}=r\text{N*ln}\left(\frac{K}{N}\right)$
Monod	$\frac{\mathit{dN}}{\mathit{dt}}=r\left(K-N\right)$
