Table 2.

Best fitting curve $C_{T} (t)$ to the known number of COVID-19 cases across the three phases of the epidemic from March to October 2020 in Ireland

Epidemic wave	Curve	R squared	F, P
Wave 1, increasing phase	$C_{T} (t) = 0 \cdot 565 t^{2} - 11 \cdot 194 t + 48 \cdot 328$	0.968	656.686, <0.001
Wave 1, decreasing phase	$C_{T} (t) = 0 \cdot 419 t^{2} - 76 \cdot 745 t + 3581 \cdot 727$	0.985	1403.117, <0.001
Wave 2, increasing phase	$C_{T} (t) = 0 \cdot 136 e^{0 \cdot 037 t}$	0.946	2266.953, <0.001
