Goodness of fit for exponential and linear growth patterns.

Linear (y = ax+b) and exponential (y = Aebx) functions were fit to the bound and mode data of Figure 5A. Analysis was limited to data between 0 and 240 min, after which the population loses synchrony and is bimodal. The goodness of fit is determined by R2, or the coefficient of determination, which measures scatter surrounding a fitted function. Higher R2 values indicate a better fit and all populations from Figure 5A are better fit by the exponential function.
