This data package includes several files. File "AA1.csv" includes all aphid abundance data from the experiment, including juvenile aphids ("juv"), adult aphids ("adults") and winged aphids ("wings"). The infection data are in a separate file, "inf.data.csv". "AA.eg.moods.R" explores example simulations of each model. "AA.model.fitting.R" fits the models to the data. Results of the model competition are printed in "model.competition.phase.A.csv" and "model.competition.phase.B.csv". Bootstrapped confidence intervals from the best model are saved in "best.model.w.CIs.csv". The data and model fits are plotted in "AA.plots.R". Performance of the model fitting machinery is assesed in both "AA.profiling.R" and "AA.simulated.fits.R".
