Dose response calculation for binomial regression models

Usage

PD(
  model,
  intercept = 1,
  slope = 2,
  prob = NULL,
  x,
  level = 0.5,
  ci.level = 0.95,
  vcov,
  family,
  EB = NULL
)

model: Model object or vector of parameter estimates
intercept: Index of intercept parameters
slope: Index of intercept parameters
prob: Index of mixture parameters (only relevant for zibreg models)
x: Optional weights length(x)=length(intercept)+length(slope)+length(prob)
level: Probability at which level to calculate dose
ci.level: Level of confidence limits
vcov: Optional estimate of variance matrix of parameter estimates
family: Optional distributional family argument
EB: Optional ratio of treatment effect and adverse effects used to find optimal dose (regret-function argument)
