Listing 7 parameters

TitleEstimated parameterDescriptionBottom range for estimationTop range for estimation
h0dimensionless parameter quantifying the initial physiological state of the population. From that, the lag time lambda can be calculated as h0/mu.
mcurvature parameter to characterize the transition from the exponential phase
μ max.maximum specific growth rate
vcurvature parameter to characterize the transition to the exponential phase
y0initial population density
ymaxasymptotic for the population density
