There is an error in the definition of priors used in Bayesian analysis of the newly proposed model of tumour growth dynamics in our published paper. Instead of the reported exponential priors for λ parameters with a mean of 100 μm, as defined in equation (15), a mean of 10000 μm was used by mistake. This resulted in overly spread model posteriors. All model predictions from erroneous posteriors match the data well, however estimated parameter values are outside of reasonable ranges.
