Figure 4:

Two ways of improving the estimation accuracy for the birth rates $b$ when cell number data is used. In (a), we show how the estimation accuracy for the birth rate $b_1$ improves as the number of experimental replicates is increased. In (b), we compare the estimation accuracy for the birth rate ${\mathbf{b}}_1$ and the net birth rate ${\lambda }_1$ depending on whether data on the number of dead cells at each time point is included in the estimation or not.
