plot.evppi

Plot EVPPI estimates as simple dot or curve plots.

Methods to calculate the expected value of information from a decision-analytic model. This includes the expected value of perfect information (EVPI), partial perfect information (EVPPI) and sample information (EVSI), and the expected net benefit of sampling (ENBS). A range of alternative computational methods are provided under the same user interface. See Heath et al. (2024) <doi:10.1201/9781003156109>, Jackson et al. (2022) <doi:10.1146/annurev-statistics-040120-010730>.

<dd><code>"dots"</code> for a dot plot of the EVPPI by parameter. If <code>x</code> includes multiple
willingness-to-pay values for the same parameter, these are shown as multiple dots.

parameters distinguished as different curves. This is only applicable if there
