Integral vs Time for singles:
Use the p-values from the regression analysis to decide which fit is better. The smaller the p-value the better the fit.
Black Line:y=-0.00614762*t+0.90238 Half-life:162.7+/- 18.6 days
Green Line: y=-0.00626604*t+0.881547 Half-life: 159.6 +/- 8.79 days
Integral vs Time for coincidence:
Black Line: y=-0.00926265*t-4.17913 Half-life:107.96 +/- 20.3 days
