Figure S1 - Comparison of empirical size distribution data with size distribution models. Both panels show empirical frequency distributions for integrin cluster size in cells adhering to 5 μg/mL Fg. (a) shows the fitted lognormal distribution and corresponding parameters along with their 95% confidence intervals determined via maximum likelihood estimation, which in this case provides a better fit to the data than least squares estimation. (b) shows the fitted exponential distribution and corresponding parameter along with its 95% confidence interval determined via least squares estimation, which in this case provides a better fit to the data than maximum likelihood estimation.
