The ability of Model A to return known parameter values. Estimated values for \( \beta \), the proportion of mosquitoes repelled from houses using spatial repellents (top row). a-d Estimates by mean distance between households moved by diverted mosquitoes (a), by proportion of mosquitoes repelled that go to households as opposed to elsewhere (b), by the number of households using spatial repellents (out of the total of 30) (c), and by the total number of mosquitoes collected from all households per day (d). The horizontal lines represent the different known values to be returned coded by colour: red (0.1); blue (0.3); black (0.5); and brown (0.8). e-h Estimated values for λ, the mean distance between households moved by diverted mosquitoes (middle row) by the proportion of mosquitoes repelled from houses using a spatial repellent (e), by the proportion of mosquitoes repelled that go to households as opposed to elsewhere (f), by the number of households using spatial repellents out of a total of 30 (g); and by the total number of mosquitoes collected per day from all households (h). The horizontal lines represent the different known values to be returned coded by colour: red (0.05 km); blue (0.2 km); black (0.3 km); brown (0.5 km); and grey (0.8 km). il Estimated values for \( \varphi \), the proportion of mosquitoes repelled that go to households as opposed to elsewhere (bottom row) by the proportion of mosquitoes repelled (i), by the mean distance between households moved by diverted mosquitoes (j); by the number of households using spatial repellents on any given day (k); and by the total number of mosquitoes collected from all households per day (l). The horizontal lines represent the different known values to be returned coded by colour: red (0.2); blue (0.5); and black (0.8). The boxplots represent the estimated values from 100 simulated datasets for each scenario. The reference scenario is based on the trial design and trial house coordinates and is given in Table 2.
