MCMC simulation for PBPK model for women of productive age with random parameters

Code for calculating estimates of daily intake of PFOA and PFOS from measured blood concentrations (reverse dosimetry) for women of reproductive age.
The original data remain undisclosed because of a confidentiality agreement associated with the study.

-> run main.m
-> MCMC simulation for the fictional data "pfoa_data_artificial.xlsx" or "pfos_data_artificial_xlsx" will be done for PFOA and PFOS
-> For rows from this data a sample of intakes is simulated (here initially the sample size is set to 5000)
	-> These results can represent the posterior distribution for intake of reproductive age women for PFOA nad PFOS
-> getRandParams.m returns the selected sample of the random parameters from their respective distribution
-> These parameters are an input into the PBPK model: "pbpk_productive_rand_params.m"
-> For every single intake estimation MCMC run, "metropolis_hastings.m" is performed with set number of iterations (initially 1000)
	-> Within every iteration the PBPK model "pbpk_reproductive_rand_params" is evaluated
