Draw parameters with random effects

Draws parameters directly from model_pars for the antibody model with random effects. Parameters are drawn randomly from a distribution with mean and standard deviation specified within model_pars.

draw_parameters_random_fx(
  i,
  t,
  x,
  demography,
  biomarker_states,
  model_pars,
  ...
)

Arguments

i

individual

t

time

x

exposure

demography

demography information

biomarker_states

an array of true biomarker quantities for all individuals across all time steps and biomarkers

model_pars

tibble of biomarker (antibody) kinetics parameters with variables: 1) exposure_id: numeric exposure ID; 2) biomarker_id: numeric biomarker ID; 3) name: the character name of the parameter; 4) mean: numeric mean of this parameter distribution; 5) sd: the numeric standard deviation of the parameter distribution; 6) distribution: character description of the parameter distribution type (e.g., log-normal, normal)

...

Additional arguments

Value

A tibble with the simulated parameters for this exposure event
