The residence matrix, \(\cal J\), holds information about residency for each human population stratum. It is the template for the time spent and time at risk matrices, making it possible to compute mosquito parameters describing blood feeding, the mixing matrix, and terms describing transmission.
Value
the residence matrix, denoted \(\cal J\) where \(\left|\cal J\right|= n_p \times n_h\)
Details
Information about residence in a patch location for each stratum is passed as the residence vector, an ordered list of patch locations. If the \(i^{th}\) stratum lives in the \(j^{th}\) patch, then \({\cal J}_{j,i}=1.\) Otherwise, \({\cal J}_{j,i}=0.\)
Since \(\cal J\) is a matrix, it is readily used for computation. Let:
\(n_h = \)
nStrata, the number of population strata;\(n_p = \)
nPatches, the number of patches.
If \(w\) is any vector describing a quantity in strata (i.e., \(\left|w\right|=n_h\)), then $$W={\cal J}\cdot w$$ is a vector that has summed \(w\) by residency for the strata, and \(\left|W\right|= n_p\).
