sample_grid_scan: Sample Grid Scan

In mrc-ide/squire: SEIR transmission model of COVID-19

Sample Grid Scan

Description

Take a grid search produced by scan_R0_date and sample n_sample_pairs from the parameter grid uses based on their probability. For each parameter pair chosen, run particle filter with num_particles and sample 1 trajectory

Usage

sample_grid_scan(
  scan_results,
  n_sample_pairs = 10,
  n_particles = 100,
  forecast_days = 0,
  full_output = FALSE
)

Arguments

scan_results	Output of scan_R0_date.
n_sample_pairs	Number of parameter pairs to be sampled. This will determine how many trajectories are returned. Integer. Default = 10. This will determine how many trajectories are returned.
n_particles	Number of particles. Positive Integer. Default = 100
forecast_days	Number of days being forecast. Default = 0
full_output	Logical, indicating whether the full model output, including the state and the declared outputs are returned. Deafult = FALSE

Value

list. First element (trajectories) is a 3 dimensional array of trajectories (time, state, tranjectories). Second element (param_grid) is the parameters chosen when sampling from the scan_results grid and the third dimension (inputs) is a list of model inputs.
