mcmc_prelim_fit
mcmc_prelim_fit.Rd
Test multiple sets of parameters randomly drawn from range between maximum and minimum values in order to find approximate values giving maximum posterior likelihood

Arguments
- n_iterations
= Number of times to run and adjust maximum/minimum
- n_param_sets
= Number of parameter sets to run in each iteration
- n_bounds
= Number of parameter sets (with highest likelihood values) to take at each iteration to create new maximum/minimum values
- params_data
TBA
- input_data
List of population and vaccination data for multiple regions (created using data input creation code and usually loaded from RDS file)
- obs_sero_data
Seroprevalence data for comparison, by region, year & age group, in format no. samples/no. positives
- obs_case_data
Annual reported case/death data for comparison, by region and year, in format no. cases/no. deaths
- mode_start
Flag indicating how to set initial population immunity level in addition to vaccination
If mode_start = 0, only vaccinated individuals
If mode_start = 1, shift some non-vaccinated individuals into recovered to give herd immunity (stratified by age)
If mode_start = 2, use SEIRV input in list from previous run(s)- time_inc
time increment in days (must be 1 or 5)
- n_reps
Number of repetitions
- enviro_data_const
Data frame of values of constant environmental covariates (columns) by region (rows)
- enviro_data_var
List containing values of time-varying environmental covariates (TBA)
- deterministic
TRUE/FALSE - set model to run in deterministic mode if TRUE
- mode_time
TBA
- mode_parallel
TRUE/FALSE - indicate whether to use parallel processing on supplied cluster for speed
- cluster
Cluster of threads to use if mode_parallel = TRUE
- plot_graphs
TRUE/FALSE - plot graphs of evolving parameter space '
