Structural Parameters

Some elements of model structure can be configured in xds_setup

Basic Setup with xds_setup()

Patch Dynamics

The number of patches is set by passing

  • Default: nPatches=1

  • e.g. xds_setup(nPatches=2)

  • Note: if nPatches \(> 1\) then it is necessary to configure Spatial Dynamics including matrices describing mosquito dispersal and a matrix for humans describing time spent / time at risk

Aquatic Habitats

  • nHabitats – aquatic habitats are located in a patch, so they are set up by passing a membership vector, a vector of integers indexing the patch where the habitat is found and nHabitats \(= \mbox{length}(\) membership \()\).

    • Trivial: By default, Lname = "trivial". If nPatches \(>1\) then the function must return a vector of length nPatches

    • Default: membership=c(1)

      • e.g. membership=c(1,1,2,2,2) sets up 2 habitats in patch 1, and 3 habitats in patch 2

      • Constraint: Each habitat must belong to a patch, so \(\mbox{max}(\)membership\()\; \leq\) nPatches

      • Note: Some patches can have no habitats

Human Population Strata

  • nStrata –

+ `nHosts` $(=1)$  

+ `nVectors` $(=1)$
