httkpop_mc | R Documentation |
This is the core function for httk-pop correlated human physiological
variability simulation as described by Ring et al. (2017)
(doi: 10.1016/j.envint.2017.06.004). This functions
takes the data table of population biometrics (one individual per row)
generated by httkpop_generate
, and converts it
to the corresponding table of HTTK model parameters for a specified HTTK
model.
httkpop_mc(model, samples = 1000, httkpop.dt = NULL, ...)
model |
One of the HTTK models: "1compartment", "3compartmentss", "3compartment", or "pbtk". |
samples |
The number of Monte Carlo samples to use (can often think of these as separate individuals) |
httkpop.dt |
A data table generated by |

The Monte Carlo methods used here were recently updated and described by Breen et al. (submitted).
A data.table with a row for each individual in the sample and a column for each parater in the model.
