R Documentation

Compute weight matrix using empirical Radon-Nikodym derivative (with fixed breaks)

Description

Compute matrix describing the weights for each parameter sampled, for each location. One row per sample, one column per location. Each weight is computed based on the empirical Radon-Nikodym derivative, taking into account geostatistical prevalence data for the specific location and the prevalence value computed from the transmission model for the specific parameter sample.

Usage

compute_weight_matrix_histogram(
  likelihoods,
  prev_sim,
  amis_params,
  weight_matrix
)

Arguments

`likelihoods`	An n_sims x n_locs matrix of (log-)likelihoods NB: transpose of slice of array.
`prev_sim`	A vector containing the simulated prevalence value for each parameter sample. (double)
`amis_params`	A list of parameters, e.g. from `default_amis_params`
`weight_matrix`	A matrix containing the current values of the weights.
