Transmission rate calculation, in model with delay to treatment — solve_lambda_vivax

Solve the equation for lambda, vivax model with CM, vector control and importation

solve_lambda_vivax_delay(
  h,
  r,
  f,
  gamma,
  alpha,
  beta,
  rho,
  sigma,
  p,
  omega,
  return.all = FALSE
)

Arguments

h: daily incidence
r: blood clearance rate
f: relapse frequency
gamma: liver clearance rate
alpha: effective treatment probability
beta: probability of liver clearance
rho: observation rate
sigma: delay to treatment (1/duration of the delay)
p: proportion of imported cases
omega: vector control intensity. If vector control is not the purpose of the analysis, omega can be fixed to 1.
return.all: if TRUE, returns lambda, I and delta. If FALSE, returns only lambda

If return.all=TRUE, returns a list with lambda, I and delta. If return.all=FALSE, returns only a lambda value
