The lower 0.9 HPD limit, mode, and upper 0.9 HPD limit for three parameters, analyzed using the linear model and exponential model. The data have been simulated from growing, stable, or declining populations, as described in the text. The symbols + and − indicate whether the summary statistics have been calculated by conditioning on positive or negative log₁₀(r). Disjunct HPD regions are indicated by a and b. Parameter values with which the samples were simulated are given in the first column.
