simulate_from_data.RdUses the compartmental model to simulate a trajectory, starting from equilibrium equilibrium state or a given initial condition
simulate_from_data(
df,
from_equilibrium = TRUE,
initial_states = NULL,
f = 1/72,
gamma = 1/223,
r = 1/60,
maxtime,
year,
rcd = FALSE,
mda = FALSE,
rcd_at_baseline = FALSE
)a dataframe containing the data, with one column called I containing the proportion
of infectious individuals (I0+Il) at equilibrium, one column called lambda containing the transmission rate,
and one variable called id which identifies uniquely each row in the dataset.
Additional optional variables are:
rho (reporting rate), delta (importation rate)
intervention levels in the past (when lambda was calculated): alpha.old (effective care), beta.old (proportion of liver stage cure), omega.old (intensity of vector control)
intervention levels in the future (in the simulation): alpha.new (effective care), beta.new (proportion of liver stage cure), omega.new (intensity of vector control)
boolean indicating if the model is run from equilibrium (TRUE, default) or from a pre-specified initial condition, which should be specified in initial_states
given initial condition, as a dataframe containing the variables "Il_init", "I0_init", "Sl_init", "S0_init", "h_init", "hr_init", with one variable called id which identifies uniquely each row in the dataset. This input is not used when from_equilibrium=TRUE (default).
relapse frequency
liver clearance rate
blood clearance rate
number of time steps for simulation
if TRUE, aggregates the outputs per year (h would be in cases per person year). if FALSE, returns daily outputs (h would be in cases per person day).
if TRUE, includes RCD in the model. Default is FALSE (no RCD)
a boolean indicating if the model including mass drug administration (MDA) prophylaxis should be used. Default (FALSE) is the model without MDA
a boolean indicating if the model was calibrated using the RCD model (i.e. there is some RCD at baseline already). Default (FALSE) is the model without RCD at baseline
A dataframe with the simulated state variables for each parameter combination in df
If alpha is not provided in df, alpha=0. If beta is not provided in df, beta=1. If rho is not provided in df, rho=1. If omega is not provided in df, omega=1. If delta is not provided in df, delta=0.
