Specify a deterministic sensitivity analysis for a budget impact model

Defines parameter ranges for a deterministic sensitivity analysis (DSA) on a bim_model(). Each parameter is varied individually from its low to high value while all others are held at their base case value.

Usage

bim_sensitivity_spec(
  prevalence_range = NULL,
  diagnosed_rate_range = NULL,
  treated_rate_range = NULL,
  eligible_rate_range = NULL,
  new_drug_share_range = NULL,
  drug_cost_multiplier_range = c(0.85, 1.15),
  extra_params = NULL
)

Arguments

prevalence_range

numeric(2) or NULL. Low and high values for disease prevalence (proportion).

diagnosed_rate_range

numeric(2) or NULL. Low and high values for diagnosed rate.

treated_rate_range

numeric(2) or NULL. Low and high values for treated rate.

eligible_rate_range

numeric(2) or NULL. Low and high values for eligible rate.

new_drug_share_range

numeric(2) or NULL. Low and high values for new drug market share (applied uniformly across years).

drug_cost_multiplier_range

numeric(2) or NULL. Low and high multipliers applied to the new drug cost (e.g. c(0.85, 1.15) for plus/minus 15%). Default c(0.85, 1.15).

extra_params

Named list or NULL. Additional parameter ranges as named elements, each a list(label, base, low, high).

Value

An object of class bim_sensitivity_spec.
